bushmeat

+1 for the poncho. Shot a bunch of matches in the rain. Found out that muzzle brakes trap a lot of water and throw POI off.

For my 18" barrel, I have an accuracy load of AA2460 with 77 SMKs or Nosler CCs. I load the same powder charge for 55s and get good performance out to 200. However, it does get a little sooty. Because you also have shorter barrels, you could standardize with 69 SMKs (instead of the 77s) and 55s for all 3 guns and use the faster Win 748. The latter powder straddles the 55 and 69 weights very well.

Have a 1/7 twist barrel. Have shot Hornady 55FMJs in it for 3gun for the past 3 years. Even shot a 100 50gr Vmaxes in it when supplies were tight. All made nice clean holes in paper. None disintegrated when exiting the barrel. Did hear some time back of a bad run of Montana Gold 55s. But, that was a bad run and shouldn't be used as a sweeping generalization.

Wouldn't slinging rifle "muzzle down over the strong side ass cheek" risk snagging the pistol out of the holster?

Yes. Definitely more reliable than Saiga. Have 3 buddies who run them for 3gun. When I got mine, I had some stoppages testing with various ammo early on. Then I ran a box of heavy shot (Rem 1330fps 1.25 oz #6s) through and that seemed to get it broken in. It's been reliable with Win AAs and Rem STS #7.5s at 1300fps in matches past two months. Have been unwilling to risk going lighter as weather's been pretty cold. You might have to tweak the SGM mags a bit, clearancing where they come in contact with rivet heads inside Vepr magwell.

Whatever powder and charge weight you're using for your long range load - just put a 55 Hornady FMJ on top of it. If your scope is zeroed at 200 for your long range load, the 55 should hit pretty close to POA at 100 and be pretty soft.

I shot 3 position rifle NCAA Division 1 decades ago. A 10/22 or the Ruger will not be much help. The weight and balance will be all wrong. Anschutz 64 standard rifle might be the best compromise without breaking the bank. Or something like a Feinwerkbau Air Rifle set up for 10 meter offhand. Some of these were set up as lefties. These would come with the sights too which would make her transition easier.

If it's shot out, it wouldn't do MOA on the first few groups. It's a lightweight barrel. Probably just heating up.

My SPR is a 5.56 which has a longer throat than .223 or Wylde. Also bear in mind the TMK is slightly longer with a different ogive. The base is in about mid-shoulder and I get 2800 fps wth just a slightly flat primer and no marks.

If you reread the OP, he was talking about loading 77s longer than mag length. The TMKs just came out a few months ago. Wait a bit. Others will start loading them long too.

5.56 AR. Isn't that what this thread's about?

I have a PredatAR barrel that's .625 at the gas block and run an SLR Sentry 6 set screw. Lots of clearance under an ALG EMR handguard which has an OD of 1.75".

I loaded 77 TMKs to 2.482 OAL. Shot 5 rounds touching, 0,4" at 100. Before this, none of my 77 loads shot tighter than 69 SMKs.

Willing to bet you'll hit more with the FAL resting on a barricade than not.

Brileys are made for clay shooters who rest their chokes on their toes. Get some Carlsons extended. Tougher, cheaper too.

If you're coming from a PRS background, you won't like how the 55s group at distance. As for gaming considerations, far steel move more and ping louder when hit with 69s and 77s than with 55s. I run 55 Hornadys at 2600 fps for 100 yards and in and 77 Noslers at 2700 for anything further. My rifle is zeroed to my 77s at 200 yards. My 55s hit half an inch low at 100. Win 748 is good for 55s and 69s, not so with 77s. CCI 400, in my opinion, is too soft for the heavies.

Mberry, I can speak from previous experience. I had a bipod spud on my bottom rail (that I slip a Versa-Pod bipod on for zeroing and shooting DMR matches). At last year's FNH, an RO told me that if my spud touched a barricade or prop port, I would go to Open. I took the spud off.

Found that when my fiber optic is bright, my poi is high.

Picked up a Savage 114 in .270 Win from a pawnshop for $300. Put a Vortex Viper 6.5-20x50 on it for $400+. Got a Blackhawk bipod from Wal-Mart for $50. Stuffed old T-shirts into a Levi's pant leg to use as a shooting bag. Shoot in area farm matches that go out to 900 yards. Beat a lot of more expensive rigs.

Get an LE Wilson case gauge, and fully read the instructions, before you go further.

Congratulations on spearfishing the grouper, Kurt. It's even more exciting if you tie them to your waist and let the blood circulate in the water a bit,

Depending on how the ridgeline is shaped, it can also crush a few knuckles on your trigger hand. You are locked in place, though. So, you might want to just take the pain.

I've been running an SLP with a 24" vent rib for five years. Most important piece of advice I got on it came from Tommy Thacker. He said that, unless I was prepared to continually mess with it, I should leave the lifter alone. He suggested I refine my loading technique to avoid getting bit. When I went to load two, I never snagged a thumb again. All I added to the gun was a Nordic +2 extension. Because of its one-piece magazine tube, the SLP is accurate and consistent with slugs. The vent rib also gave me same POA/POI with 1200 Rem Gun Club or 1300 AA #7.5s from 7 to 30 yards on steel or clay targets. I run the heavy piston in mine so I can use the occassional 3" #6s. Haven't broken the original piston yet. The lighter piston would run the 1145 AAs. Have a lot of buddies who also had SLPs. They had their lifters welded and then had to have other things done to the gun (along the lines of AustinWolv's post), then gave up and now shoot Benellis. No, the loading port on the "updated" blue gun is not opened up. It's ok for loading twins, not for quads. IMO, I wouldn't suggest hogging it out as there doesn't seem enough meat on the receiver. Also, the forend would have to be reprofiled if you wanted to load quads. The current offering comes with only one bronze piston. Some SLP shooters have been having problems with that.

+1, particularly on the long range.

Figure out how well you shoot slugs and what your holds need to be out to 110 yards. Confidence in your hits makes it easier to plan whether to load extras or not.
