62 grain due to the steel core. It's NATO spec stuff. I keep a bunch of it on hand. Good stuff, but it has the tendency to eat steel targets.

The twist in your barrel is the big difference in which grain bullet fires more accurately from your rifle. Mine is a 1/9,and loves the 62 grain. Im not sure if that's how its supposed to work,but it does. I was going to try a different twist in my new rifle,but went with the same. And yes the steel core is awesome stuff,but flying at 3000 fps,it will defeat most other steel that is holding still.

I can only imagine, this is my 1/4" steel spinning target with some holes left by some 55 grain PMC .223 its got a couple more now from a further distance with the XM193 I tried out the other day. The 55g will almost punch through 1/2" steel, so I imagine the 62g will go all the way through with ease. My barrel is 1/8.

Just got some 2" plate,in a 12"x12" square. plan is to see if .308 APIs will kill it or not. Once its all beat up,Ill throw it in the tractor weight bucket. Thing must weigh 80 lbs.

 
Ok guys save your brass. I will buy it.

$10/100 of .223

$10/100 of 308.

$5/100 9mm

The 1:7 barrels like the heavier grain bullets, 55-80gr is good.

The 1:8 barrels like the middle grain bullets, 48-68 is good.

The 1:9 barrels are for the light grain bullets, aka varmit super flat loads. 40- 55. These all overlap a bit.

If I shot a 44 grain from my 1:7 barrel it might spin so fast it would disintegrate shortly after leaving the barrel. If I shot a 77 grain from Smelt's 1:9 barrel it would wobble, wander, and possibly key hole on impact or tumble. The heavier bullets will remain more stable the further you try to shoot. The lighter bullets will retain velocity longer the further they go compared to the heavys, but they will drift with lighter wind. that's the beauty of the .223/5.56. There are loads and barrels for every application you can think of. My son and I will be reloading 75gr Hornady boattails. According to the charts it should be very good for High Power slow fire competition with my 1:7 barrel. Should carry out to 600 yards with predictable drop. For woodchucks way out on the field a 50gr would be good, for deer or people at 0-200 yards a 55-62gr would be good. For punching the lights out of a mosquito at 600yards 77 gr would work.

Be aware some ranges do not allow the NATO/Federal/Lake City 62gr. steel core stuff because of the steel core. Some of the Wolf (also steel core) is not allowed. But its hard to enforce that stuff.

I've got a plate somewhere with a few holes in it. It started as a trick shot, I made the plate jump with the Mosin, then sunk a 30.06 thru it, then a 303 Brit, then a 308. Its a pretty neat souvenir. I labeled all the holes.

That Federal/lake city 55gr shoots nice. We did our clinic at 200yards with it and I was sinkin it in the black. Not too shabby for not shooting 200 yards in more than 20 years. I also did the 3 gun match with it. No misses, not malfunctions.

Got 500+ .223/5.56 brass depending on how much more I shoot today. Any interest in .45?

Shot ~200 rounds today with the AR15. Performs well, but I had 2 failure to loads that I don't know if they should concern me. It happens mid-mag (pmags) and basically a round fires, ejects, and the next round doesn't quite chamber correctly. With PMC I would need to pull the charging handle back and eject the load. Today on XM193 the round would get caught, but as soon as I bumped the rifle it would drop in the chamber. I grabbed a couple of pics of one of the rounds, not sure if it is something that needs to be "broken in" or if there is something wrong in the setup. Or maybe it simply happens from time to time, although if a 1 in 100 failure rate is common Im a bit worried. The bolt cycles and locks back when the mag is empty, which makes me not think short stroking. The rifle had ~500 rounds through it before putting the new BCG in, and there are about 200 rounds on that. It has done it on both BCGs with 2 types of ammo. Any thoughts?

Try a different mag in it. A Pmag solved all of my FTF woes instantly. Mine was doing just that until switched. My old aluminum mags ran all day in my carbine,but the new M4 style carbine wouldnt have any of it. New bolt vs old bolt doesn't catch the round the same...maybe a little dry inside....these things can be really finicky when they feel like it.

To everyone thinking about shooting at heavy steel plate with steel cored bullets: don't! Not unless you have a death wish. Remember that if it doesn't go through, it comes back. I had a steel core from a mosin nagant come back and hit the tree directly behind me and a mere couple feet above my head. This is what happened: bang. Ding. Whistling... *hit the ground!* twap and then a piece of bark falling. Not cool. Don't do it.

 
I have a handful of pmags and 1 old mag, and I think it has only done it with the pmags. Granted I have a 5 of them and 1 metal mag, so the odds are much greater anyways. And I was running it fairly wet, because of the new BCG.

^Agreed. I have seen ricochets myself.None that close,other than a few birdshot pellets coming back to say hi. When I shoot thick plates,its a pretty controlled deal. Plates are angled down slightly,hung by cable,so they swing back on impact,increasing the chance of a ricochet hitting straight down into the dirt. I only do it when I have a new round to try,just to see what it will defeat.That info goes in the book,and the ammo is stored away. Other than that,I only shoot soft nose stuff at my gongs. If you want to shoot something fun,get some tannerite....

 
Looks like the bolt is scraping the case. Like the bullet isn't coming up high enough so the bolt edge can knock it forward. The bolt misses the rim and digs into the case body...or the rear of the mag/follower is hanging up.

 
From what Ive been reading, its either the mags are slow, not consistantly getting the round up into position. Or the bolt is fast, not giving it enough time to get the next round into place.

Do mags need to be "broken in"?

I was at Northeastern Firearms yesterday trying to make a concealed carry decision. I have the G21 SF which I like and shoot comfortably. I was thinking of staying with Glock, and getting either the G30 or most likely the G36 for concealed carry. They have way too much to drool over.

Mags are usually good from the start, especially basic stuff like the ar15 mag. Might try a different buffer spring, I have a Spikes you can borrow. Might try depressing the follower on the mag and see if you can get it to tilt or hang up. Number your mags and just note which mag was in when the malfunction occurred. Paul at Northeastern could help.

Heres my latest AR configuration. I'm just prepping for High Power competition. Colt HBAR 20 heavy barrel upper with A2 1/4 MOA sights on top for the Spike Tactical lower and M1 Garand sling. May19th I'm going to see what I can do at 600 yards.

Could be the buffer, I cycled all of my mags a bunch of times and will be numbering them to try to pinpoint. Its in Paul's hands right now, he's fixing the set screw. He's going to give it a good look over and some test firing before I pick it up on tuesday.

 
I bet you shoot with my buddy Nate. He has a 600 yard AR,a couple of M1a's,does a lot of 3 gun last I knew. Also,have you tried a Magpul PRS stock on one yet? Im thinking real seriously of putting one on my AR-10,and maybe on one of the 15s,if I get a rifle upper. Best stock I have put to my shoulder. Once all my other priorities are out of the way,Im going to try a 3 gun shoot for fun. I just need some practice with my FN12,its the only non-magazine shotgun I have.
