Well, your subliminal message might not work when you mount your scope mounts backwards. And, don't bridge the rail. You might want to fix that before you shoot for groups on Sunday. I'm just sayin... Fuckin Twilight Zone in here tonight, WTF.

^^^ THAT. FUCKIN. ROCKS. Hands down.

Your scope mounts are on backwards. And, you don't bridge the rail. You should fix that before you go shooting for groups on Sunday. I'm just sayin'...

Gun Pusher just called... "Hey man, all your SHIIT came in. A couple days ago..." Me -"A COUPLE DAYS AGO?..." Him - "Yeah, I was out of town. People are looking at it, how much you want me to sell it for?..." Me -"I'll see you first thing in the morning, how much do I owe you?" Him -"I don't know, I didn't even add it up yet." Me - "Alright, see you in the morning, I'm loading ammo tomorrow afternoon..."

Man, where you are, we should have drone footage of the awesome beaches!!!...

From what I've been able to dig up, the 1:10 twist has been stabilizing heavier .257 projectiles in the .250-3000 Savage for years. They didn't mess with a good thing. It did a good job stabilizing that 87gr projo out to 800, and worked in the past on similar trajectories, so I'm okay with it.

Need some clarification, Rene... Me and Sisco wanna know...

I found that last night and was shocked - I didn't think you'd be able to dial up the mil drop for 800, and hit with this cartridge. Especially the 87gr factory ammo. I was already committed - my barrel and dies should be here anytime now. SS, welcome to the family, brother!

That's the specs on the M110A1, Mike, compared to the original M110...

The 25-45 Sharps at 800 yards... Not a typo...

.308 Win. SS's barrel, I'm talking about.

I tried to bait them, too, and no takers... They know...

Nothing, really. There are no drawbacks to that twist.

Here's a report vs. whitetail http://ar15hunter.com/forum/index.php?/topic/23-25-45-sharps/ There are many more testimonials on www.quarterbore.net. It's quite the deer cartridge, man. http://www.quarterbore.net/forums/showthread.php?t=9418

I think we're about to throw down some Myth Busters shiit in here...

Now, when I look UBERclose at that pic, those two cam pin slots MIGHT be in the exact same location, front to back... Pic lighting and an oil smudge make the Armalite look further back than the DWilson...

My take on that is no, but there is a difference in the bolt, and that's giving the perception of what you see. My reasoning for that is: Both those bolt faces are flat on the table, and both those carrier body fronts are at the same height. So, the bolt drops back in the carrier, into the firing position, to the same depth. If they didn't, then some serious other things would have to come into account, primarily manufacturing barrels for headspace... However, that cam pin slot is definitely different on the two types. Only way for that to happen is: that cam pin hole n the bolt is in a different place on the Armalite and the DPMS-based. No other way around that, I'm thinking. If the hole was not in a different place, and the same on both those bolts, you couldn't get away with having the cam pin slot in a different place, or different depth (front to back). My reasoning sound logical? I'm guessing, based on what I see, but it makes sense in my mind...

New(er) from Hexmag - Rainier Arms is pricing them at $17 each, and I haven't looked anywhere else yet. Quite the affordable option for the Big ARs. *** Be advised, directly on the Hexmag website, these are listed as "AR-10 Magazines." If you're an Armalite owner, you know the difference already. They're not really "AR-10 Magazines..." Be forewarned. https://hexmag.com/ar-10-magazines FDE flavor, as well...

Of interest - on both your flavors of "BIG BCG" here, the front of the carrier, the bolt height when in the firing position, AND the shelf that the charging handle grabs onto - are all in the very same position. The gas key is in a slightly different location, and the cam pin channel in the carrier body appears to be in a slightly different position. This all affects timing in the direct impingement system, and it's just two different ways or techniques to accomplish the same thing...

Nice score, man!

^^^Awesome! Have then wait for the bunny!!! Happy Easter, guys.

^^^ Interesting, Jim - big time. In MY pics, that 308 BCG was a DWilson, as well, compared to the AR15. Here, in yours, it's Armalite AR-10 on left and DWilson DPMS-based on the right - and the Armalite is even further back than the DWilson. So, with the Armalite AR-10 compared to the AR15, there would be a bigger difference... and a greater need for a longer gas tube, in order to properly cycle the weapon. The bottom line of "normal" in all this was before everybody and their brother decided to jump into the Big AR World here. People mostly did it right, on parts. Doesn't matter is a barrel maker drilled the gas port in the DPMS position, or the Armalite position, on the barrel - they told you if it was out of the ordinary, and make certain to use "xy" gas tube. Now, people that are making barrels, and gunsmiths in shops, don't even know there's a difference to begin with - it's gotten that bad. "Normal" was that the gas tube comes back to the center of the cam pin cutout in the upper receiver. If you had a DPMS-based barrel, it just uses AR15 gas tubes and comes back to that location. If you had an Armalite AR-10 based barrel, and used a short gas tube, it doesn't extend to the correct position. The fix is easy enough - after diagnosing why your rifle runs like shiit sometimes, but works great with other ammo, and drilling gas ports up, and adding adjustable gas blocks (which DO NOT help this situation...). You get my point... I think we should move this thread to one of the technical sections, then pin it...

Yes, definitely. I've had one in my DPMS (actual DPMS) LR308 upper receiver/rifle since 2012, I think.
