Two students injured (shot), gunman dead. SRO reacted/pursued immediately, got a round off, gunman shot at him, but didn't hit him. They're still trying to determine if it was the SRO's round that got the gunman.

Here are the dope charts I worked up on both the Grendels. I will confirm and test these at various others distances coming up soon. These charts are about right on, based on what I saw at 500 and 845 yards. I'll confirm with accuracy shots at other distances, instead of "shots that can hit steel" at those distances. This is all used to refine what my handloads are really doing - but they're really close this (and right on at 845) for what we saw this weekend. 18" Grendel, 123gr ELD-M at 2585fps from the handloads delivered this on target: 12.5" Grendel, 123gr ELD-M at 2370fps delivered this on target:

@Matt.Cross, get in here, brother, and tell some tales...

So, Matt and I drive down there, and this guy is shooting pistol on a small silhouette - and doing damn well, I might add. Tight group in the center of that little plate. He's about 75 or 100 yards short of where our target was, in relation to camp. We drive right up to the base of the hill, Matt waves at him when we're rolling up, and we get out and walk uphill... I don't know if he really saw that white-painted steel or not, but when we were walking up the hill, he looked kinda shocked. He stopped shooting, obviously. We pulled the target, put it in the bed, and drove right over to him on the way back to camp. When we pulled up, I said, "We were shooting that thing at 605 yards, but we didn't think it was polite to shoot over you, and slightly in front of you, so we yanked it." The guy says he's sorry, and he'll move, and all that, and we just said, "No worries, man. Don't sweat it." He says he saw a few people shooting over there, and he saw a camp way to the south... I said, "That's us. We were shooting that thing from there..." You should have seen the look on him. He looked back to where the target was, looked at our camp, did it all again... then just looked at us... He says he'd move again, but we refused. I told him, "Everyone needs some training, it's no big deal. Do what you do..." We rolled back to camp. By this time, JB Matt is just sighting in guns and getting dope on all kinds of stuff he brought out there. 257 Roberts (Holy Fuk is THAT thing sweet!), and all kinds of others. We spent the rest of Sunday doing pistol drills, rifle dope gathering, and shooting JB Matt's guns. I'll let Matt get in here now and spill some stories.

It is, indeed - it is perfect ground for longer distances, brother. Just perfect. We can go 1200 yards all day long, and really studying the terrain - we can go as far as we want, really. As far as we want. Way further than any of us can shoot, and any of our rifles can shoot - even Ron's MRAD. Yep... I'll bet we've got more than 2,000 yards out there... This event went Friday ,Saturday and Sunday. I'll let Matt talk about Friday, which turned into a planning and item-gathering day. For Saturday, the whole plan was go drop the big truck and camper close to the long range site, get over there with the gear in the Nissan, and have at it. Return to base camp later in the day, set up camp, and set up targets for Sunday. So Saturday, we did just that. We dropped the Dodge and camper, proceeded in our mini-convoy (the Nissan and JB Matt's Tactical Cadillac, the Suburban). We set up the 100 zero targets just to confirm or refine gun zero's, 500 yard steel and 845 yard steel. The 500 was just another conformation target for both sighting and wind holds - just a practice target for the 845. Everything was confirmed with the range finder (more on that thing later), and the 100 was right on, the 500 was actually 513, and, well, the 845 was 845 yards. That's why we called it the 845... As soon as Matt pulled the trigger on his second shot, he was done. Mission accomplished for his shoot-goal. Go longer than last time. He was content as I've ever seen him, and smiling the whole time. That MA-TEN dope card that he had with him was right on the money - as we saw the rest of the weekend, too. I got out there right away with the 700 AAC-SD, and it did it's business as usual. I was loaded up with Hornady 178gr HPBTs in once-fired Hornady Match brass, and those loads delivered. I have another 50 rounds loaded with Hornady 195gr HPBTs in the same brass, at 2.800" COAL, to try out, and we intended to do that, but we never shot them. They're gonna get it, though. That's gonna require a whole other workup to dial them in, but it'll be fun to get the data on them. I went after the 18" Grendel next, and it was right on the money. I couldn't ask for more from it, and it'll whip the a$s of both my Mk12s, hands down. It's a completely different beast altogether. 3.0 mils of drop at 500 yards, 8.2 mils of drop at 845 yards... unreal. JB Matt worked over his long Grendel, too, and it was right on the money for him. He was working on a 223 Wylde gun and got it down at 500 yards. I got that damn 12.5" Grendel out, and that thing was a shocker. Completely. I expected it to perform at the 500, but maybe not much more than that. Holy Sheit, is that thing bad. 4.0 mils at 500 yards and 10.something at 845 yards - and it was ON at 845 yards! Once the dials were set on the scope, it made hit after hit after hit, without fail. I was floored, bewildered, and shocked that a short barrel anything could perform like that. Once we had all that sorted out, and had all the data on guns, Larry called. He was over at the "normal" location, looking for us. JB Matt was working on another bolt action at the time, so I hauled butt to meet Larry and guide him in. Larry stayed for quite awhile, and we all had some GREAT conversation! When it was time to pack up the long distance side, it was somewhere around 3:30... We pulled targets, got everything in the trucks, and hauled it all over to the other side, to camp. Once we got to the other side, Larry rolled straight through and hit the road for Tucson. We proceeded to set camp up, and put a couple of JB Matt's targets out at pistol distances. Before it got too late, Matt and I tossed a big steel out at 375 yards for some night shooting. We shot pistol,and once it got dark, we shot rifle at the 375. Got the fire going, got the brats in the beer an on the stovetop to brown up, and got the chili in the dutch over over the fire. The brats went in, we cooked it up good, and chowed down. After that was some more night shooting on the 375, and bedtime. Out. The next morning, we decided to put another bid piece of steel at the end of the ridge again, and this time it worked out at 605 yards. We proceeded to give that guy the business, and a newed silver-looking Suburban drove past camp. No kidding, that guy drove to ALMOST where our 605 target was, pulled in close to the hill, and started hauling stuff out of the back of his truck. We didn't know what to do... Matt and I were ready to ring that steel, and let the guy know that he set up close to our target. JB Matt was the voice of reason, and said, "He's driving a Suburban, he can't be that bad, let's invite him over, maybe he's cool..." We almost did it, and we RESISTED the temptation to ring that plate - but it was TOUGH... We decided to pull the target. Just drive down there and take it down. We already had 3 or 4 hours on it, so it really wasn't a loss. More coming... posting this before I lose it...

I had no idea, either!!!! This is INVALUABLE INFORMATION!!!

Try that standard rifle buffer first. Just check the outcome. As far as an ideal specification on the gas port diameter, that's all up to configuration. Running the 10oz buffer changed all that. If it runs unsuppressed just fine with the off-the-shelf ammo and the lighter buffer, then it's gonna recoil harder (but still run) with the suppressor on there - and you can adjust it down. The magic will be finding that happy medium, where it runs suppressed and unsuppressed.

Pics just in from Justice Brothers Matt!!! JB Matt's Grendel - this thing is 1/2" groups at 100 yards. Damn nice. Getting my short Grendel ready to go. This thing was a shocker. Up in the rocks. I was on that target right away, and getting after it. @Matt.Cross, hiding in the rocks!!!

Alright, here it is... The latest Heather Locklear mugshot. So, this time, she's into a lot more. http://www.tmz.com/2018/02/26/heather-locklear-arrest-domestic-violence-battery-cop/ Is she too far gone now? Or, not?...

This is telling me that your gas port in the barrel is too small. The gas is kept completely open all the time, it functions great with the suppressor (which will add some back pressure), but it doesn't run right without the suppressor - when removing the suppressor takes away it's additional back pressure. You need more Oompf when the suppressor is off, to properly cycle it, and the gas is already wide open. Easy fix - drill up the gas port diameter in the barrel. You need to close down the gas a little to get it to shoot as smooth with the suppressor - but that's the reason for adjustable gas in the first place...

The 18" Grendel was on at 3.0 mils at 500 yards, and 8.2 mils at 845 yards. Just for reference, the 700 throwing a 178gr HPBT at 2400fps took 9.0 mils to get right on at 845 yards. The 18" Grendel shoots alot flatter than the .308 Win rounds I've got cooked up for distance.

This thing. Man, lemme tell you about THIS thing!!! 12.5" 6.5 Grendel, pistol. Leupold Mark AR Mod 1 Firedot scope, 1.5~4 power. In a Nikon M223XR mount with 20 MOA built into it. Okay, so we went to the long range side this time. Been trying to get over there for every trip, and it just doesn't work out. We went there first thing Saturday morning, before setting up camp where we usually do. Parked the big truck and camper, because it won't fit in over there, hauled all the gear in the Super Nissan. Set out zero confirmation targets at 100, steel at 500, and steel at 845 yards. SO, Matt lays down on top of the 10-foot high berm, and he's just DYIN' to pull a trigger. He sights in on the 845 right away, and hits it on the second shot. I was not gonna let that go unanswered, and I got out the 700 and missed my first shot, but gonged it on the second one. Okay, draw there. I'm safe for now, even though I'm creeping up on Middle Aged... THIS LITTLE GRENDEL. It is ON THE MONEY on the 500, with 4.0 mils of elevation. It is ON THE MONEY at 845 yards, with 10.6 mils of elevation. I couldn't believe it. It wasn't like launching a round or lobbing a round - this little thing shoots FLAT!!! It was all over the 845 as soon as I got the elevation turret dialed right. Everytime. Blew my mind.

Get ready for this - this technology is a game-changer. This will be used continually, from now on.

Just because you guys are jonesin'... WAY more to follow. Did some different things this shoot. High(er) angle shooting. We'll be getting WAY deeper into this, on every shoot. I'm up in the first vid, with Justice Brothers Matt shooting to my right. Second vid is Matt.

One more vote of confidence on the Minimalist. I have one, but I'll have more.

Wait a minute - that looks like a 5.56 bolt catch...

You need to trim down the bottom corner on the bolt catch. That's hitting inside the cutout in the lower. Dothat first, so it at least lifts without binding. Let's work on the engagement once it moves freely.

Here it is, at EuroOptic, for $65. Call them on the phone and ask if it's in stock. I can very, very highly recommend EuroOptic. https://www.eurooptic.com/Armalite-AR-10-6-POS-Receiver-EXT-Kit.aspx

Armalite also has a specific buffer spring for their AR-10 recoil system - the EA1095 spring. You'll need that, too. I found out not long ago that Armalite sells the complete system as one part number, and it's significantly cheaper than piecing it together, by the three parts. The receiver extension alone is $40. The AR15 H3 buffer is about $40. Then the other parts that you get in this kit... This thing is a screamin' deal. Had I only know earlier... Sign up, and wait for it to come into stock - it won't take long. I'm impatient as hell, and I'd piece it together at the greater expense... https://www.armalite.com/product/ar10rekit01-6-position-receiver-extension-kit/ Armalite part number (for the kit): AR10REKIT01

Correct - it wouldn't be legal on this side, unless the muzzle device was pinned and welded, or 1100-degree silver soldered. We have a Fall Shoot every year - that's the BIG one! This weekend is the Spring Shoot. The hardcore guys show up for that one...

It wasn't implied - your explanation was reqeusted. If it was racial, in any way, you would have been booted. Immediately. It's that simple. Racial shiit isn't tolerated, and people aren't given a second chance to do it the second time. I hope you understand that. Thanks for the clarification. It was needed, and you gave it.

I'm asking "if there are issues running an M4-style receiver extension with rifle gas on an 18" rifle?" Which I've been told there will be short stroking issues. Fuk it, I got this. Okay, I made this two quotes, because I'm making two statements here. First, your buddy rewording your question - what's his background? Second, you want to know if there are issues running an M4-style receiver extension with rifle gas on an 18" rifle. NO, there are not. I presume that you're asking that specific question, that your buddy reworded for you, and you're referencing a 308AR platform. Is that correct? I'm not trying to be a dik, I'm just trying to make sure there's no confusion, and be clear. So, pictured below is a 5.56 rifle with rifle length gas and an 18" barrel, and an "M4-style receiver extension. This thing runs like a champ, and nothing can stop it. So, based on that, as evidence that a rifle with an 18" barrel and rifle length gas and an M4-style receiver extension, not only works, but works great... you need to know this part - a 308 .Win round is making ALOT more gas than a puny 5.56 round, and a 308AR will have NO TROUBLE running a setup just like that. Here's the 5.56 gun. The one on top. It's proven, and it's badass.

That would have been an excellent recovery...

You're right. The DPMS-based 308 carbine recoil system uses a 2.500" buffer, that's WAY too light. The Armalite AR-10 carbine recoil system uses (no kidding) AR15 carbine buffers that are 3.250" long, and are H3-weighted. They accomplish this with a carbine receiver extension that has an internal depth of 7 5/8" (instead of using the AR15 carbine receiver extension, with it's 7.000" internal depth).
