I totally get what your saying I was just thinking about the fact that some slots could be machined waay oversize. My point is the bottom of the slot in the receiver holds the catch and in turn the mag UP. The top location of that slot really means nothing as it basically just determines clearance and NOT location. I was just thinking he should be getting reference numbers on the location of the BOTTOM of that slot as that is the surface that determines the final location of the feed lips. EDIT: Maybe just get a measurement from the top surface of the lower receiver to the top of the catch would be a more relevant measurement?

Call me a dick but shouldn't you be referencing the lower portion of that slot anyway? that is the surface that essentially holds the catch and mag up. Theoretically that slot width could vary quite a bit and not mean poop as long as the bottom wall of that slot was close. Print calls for a .250 finish width so Id be willing to bet most manufacturers just sail a 1/4' end mill in there and then clean up the walls to a slightly larger dimension. If they get carried away and drop that wall too far down it may be the problem you have going on. Just my .02

Not sure if this will help but all the info I have points to 11/16" or .687" with a nominal 1/4" .250" wide slot. Same goes for the AR15 as well so if you guys are getting .650 then I would think its buried in there enough.

We have armed guards posted at banks to protect our federally insured money and that's ok. But we wont do the same to protect our children???

7.62 inside a .50bmg

Just ran those loads this morning. 38gr cycled the action fine but was definitely weak, Standard deviation seems to point to 40.5 to 41 grains which gave me an average of 2530fps with a 168gr hpbt . Ran up to 42.5 grains of varget which pushed a 168gr up to an average of 2621fps.

Thanks SS, I've been spending a lot of time over there reading. So much info I think I'm going cross eyed.

I was thinking that myself. I figured between being a nato case and a slower burning powder, not to mention probably my favorite rifle. I would chicken out and start small and see how she reacts.

I just dumped some powder charges last night starting at 38gr and working up to 42 gr of varget to test out this weekend. I recently sliced a LC case down the middle the other day. I want to do it to a commercial case to have a side by side comparison.

@survivalshop and @Sisco Ive started sizing cases and doing research on loads for my M25. I started checking available free length until I touch the lands and its almost .100" longer than the 308ar chamber I just played with. I really don't want to seat a projectile that far out, Or do I? The mag Will dictate my max but how big of a jump to the lands can I get away with? What are your opinions and or experiences? Thanks

I know, I know, it's not a true "group" as its only 3 shots but I loaded up 100 more of these to see what I can do. This was shot this morning at 120yds at about 30°f

Perfect timing SS I was just about to do some research on loading for my m25 ?

Definitely like the way varget meters. I've never tried RL15 but have heard of it. Once I get the 308ar dialed in I want to do the same with the lrb M25 and she what she likes. With a 22" 1:12 barrel I'm sure it will be different.

Thanks for the link and doing some math SS I'm liking 44 grains but currently experimenting with 42.6 - 43.5 in .1 increments. We shall see....

Primer just started to flow into the firing pin hole at 45 grains nothing crazy I could just feel a slight "burr" with my fingernail. Im going to do more playing around 43 and 44 grains so im not worried. as for Deviation and spread? You can calculate that if you like. The fps shown was what I got for each shot in each group. Although it was shot through a $100 chronograph so make of it what you will.

I finally got around to loading up some 308 for the first time. Been saving lake City, Hirtenberger, and federal brass for awhile and have had dies. Ive been reloading other calibers for awhile but first time with 308, Got around to finally ordering powder and projectiles the other day and started off with some Sierra 168gr hpbt's over some Hodgdon Varget powder. Loaded some LC brass with a rough spread from 40.5-45gr of powder to see what my 308ar was keen on. Thought I would share the results. Distance was 120yds and Barrel is a Criterion 18.5" medium weight match SS 1:10 Groups are definitely not my best and I hadn't shot this rifle in quite sometime.

OTTAWA BUREAU CHIEF – The Globe and Mail Published Wednesday, Jun. 21, 2017 8:00PM EDT Last updated Wednesday, Jun. 21, 2017 10:25PM EDT A sniper with Canada’s elite special forces in Iraq has shattered the world record for the longest confirmed kill shot in military history at a staggering distance of 3,450 metres. Sources say a member of Joint Task Force 2 killed an Islamic State insurgent with a McMillan TAC-50 sniper rifle while firing from a high-rise during an operation that took place within the last month in Iraq. It took under 10 seconds to hit the target. “The shot in question actually disrupted a Daesh [Islamic State] attack on Iraqi security forces,” said a military source, who stressed the operation fell within the strictures of the government’s advise and assist mission. “Instead of dropping a bomb that could potentially kill civilians in the area, it is a very precise application of force and because it was so far way, the bad guys didn’t have a clue what was happening.” The kill was independently verified by video camera and other data, The Globe and Mail has learned. “Hard data on this. It isn’t an opinion. It isn’t an approximation. There is a second location with eyes on with all the right equipment to capture exactly what the shot was,” another military source said. A military insider told The Globe: “This is an incredible feat. It is a world record that might never be equalled.” The world record was previously held by British sniper Craig Harrison, who shot a Taliban gunner with a 338 Lapua Magnum rifle from 2,475 metres away in 2009. Previously, Canadian Corporal Rob Furlong had set the world record in 2002 at 2,430 metres when he gunned down an Afghan insurgent carrying an RPK machine gun during Operation Anaconda. Weeks before, Canadian Master Cpl. Arron Perry briefly held the world’s best sniper record after he fatally shot an insurgent at 2,310 metres during the same operation. Both soldiers were members of the 3rd Battalion Princess Patricia’s Canadian Light Infantry. JTF2 special forces are primarily tasked with counterterrorism, sniper operations and hostage rescue. Much of the information about this elite organization is classified and not commented on by the government. The unit’s snipers and members of Canadian Special Operations Regiment, who are carrying out the main task of training Kurdish forces, have been operating in tough conditions in Iraq. The Trudeau government pulled CF-18 fighter jets out of Iraq in 2016 but expanded the military mission, which will see the number of Canadian special forces trainers climb to 207 from 69 in an assist, train and advise mission. Canadian commandos are not supposed to be involved in direct combat, but are authorized to go up to the front lines on training missions with Kurdish Peshmerga fighters and to paint targets for coalition air strikes. For operational security reasons, sources would not reveal the names of the elite Canadian sniper and his partner, nor the location where the action took place. A sniper and his observer partner are often sent to remote and dangerous locations to hunt down insurgents while having to carry heavy equipment. Once they have located the target, snipers follow the same methodical approach before each shot. Breathe in, out, in, out, find a natural pause and then squeeze the trigger. Canada has a reputation among Western military forces for the quality of its snipers, despite the small size of the Canadian Armed Forces compared to the United States and Britain. “Canada has a world-class sniper system. It is not just a sniper. They work in pairs. There is an observer,” a military source said. “This is a skill set that only a very few people have.” The skill of the JTF2 sniper in taking down an insurgent at 3,450 metres required math skills, great eyesight, precision of ammunition and firearms, and superb training. “It is at the distance where you have to account not just for the ballistics of the round, which change over time and distance, you have to adjust for wind, and the wind would be swirling,” said a source with expertise in training Canadian special forces. “You have to adjust for him firing from a higher location downward and as the round drops you have to account for that. And from that distance you actually have to account for the curvature of the Earth.” U.S. Sergeant Bryan Kremer has the longest confirmed sniper kill shot by a U.S. soldier. He killed an Iraqi insurgent with his Barrett M82A1 rifle at 2,300 metres in 2004. https://www.theglobeandmail.com/news...ticle35415651/

Thank you gentlemen.

5rds @ 125yds Sorry it took so long to get a decent group pic. Been running a lot of lake city down the pipe to break everything in and work on getting comfortable with this rifle. I got the iron sights zeroed in and then proceeded to mount some glass and play around with some different ammo. I picked up a case of some 1980's Hirtenberger surplus and wow that stuff shoots great for $.55 a round delivered! Ive yet to put any through the 308ar though. And of course the best group Ive got was with 168gr FGMM. This was only five rounds at 125yds but Im pleased. This rifle will definitely out shoot me.

I hear ya. So where did you get the slide stop? And how do you like it? It aint red but check these out....... Tritium dots too

That is an awesome story! I too have never heard of this before now. Ive met that man Jan Scruggs in person in 2007 when my stepfathers name was added to that wall. He has done so much for this memorial and continues to do so. I visit DC often as I have friends there and always make sure I make a trip to the wall to pay my respects. There are no words. My stepfather died in 2006 as a result of a gunshot wound from an AK during the Tet Offensive in 1968 LCpl Raymond C Mason 3/7/47 - 5/28/06 Panel 41E Line 64
