most accurate semi-auto 308

[Peter M. Eick]

Here is the true test of a rifle. Put a bunch or rounds down it and see how it does. The top is my Supermatch with 50 shots in each target off the bench at 100 yrds. The bottom is the NationalMatch with the same setup. Also both were shot quickly, meaning a reasonable pace, but not take a shot and let the gun cool. All 50 were expended in under 20 minutes because that would be a target change.

When I see groups of just a few shots like some above, I say they were lucky. Get some mag changes in there, get some hot barrels etc.

This is where the M1A shows its capability over conventional rifles in my opinion.

YMMV.

Having owned a PSG1 I can say they are accurate but not worth the money they command. They won't out shoot more modern offerings for a fraction of the price.

My most accurate semi-auto 308 - CHMK14SEIMOD0TS

most accurate semi-auto 308 was wondering what your guy's thoughts were on the most accurate semi-auto 308.

The AR-10/SR-25 can be very accurate for the first few shots, but if you want a gas gun that is
both accurate and reliable ... look no further than a well massaged example of the M14 platform.

I recently sold my ArmaLite AR-10 SPR to help fund another M14 build

My Crazy Horse MK14 SEI Mod 0 tactical scout shoots sub-MOA with Portuguese surplus ball ammo.
The barrel: Unlined 18.0" medium heavy, 4 groove, 1:10 ROT with M80HT.
The SAGE EBR stock tension beds the action, semi free-floats the barrel and unitizes the gas system.

Please don't use the words "accurate" and "semi-auto" in the same sentence.

If you want to learn to shoot, and shoot accurately, get a good bolt action Remington 700, with a .308-size bolt face, and get it rebarreled with a select match heavy barrel, and put one of Arnold Jewell's triggers on it.

Or you can stay with the tacticool spray and pray crowd.

Great post because it allows rants.

The most common rifle on the line at Camp Perry is the Space gun. I have witnessed National records set with these rifles. The second most common rifle is the bolt operated Tubb rifle.

For the last couple of years someone using the Tubb rifle has placed first at Camp Perry. Considering that David Tubb has been the dominant shooter at the Nationals, it should be no surprise that most of the wins with the Tubb rifle were by David Tubb. Most of the "Top Dogs" use a Tubb.

However this year, Carl Bernosky won with a rifle based on the AR. I met the designer in the pits. The cartridge was the 6 mm Hagar. http://accurateshooter.wordpress.com/2007/10/25/bernosky-sets-new-nation-high-power-record/ David Tubb, with a Tubb rifle placed second.

The great bolt guns, such as the M700 and M70, are still as accurate as ever, and the bolt dominates the long range crowd. I shot my M70 yesterday in a 1000 yard match, but after shooting my own semi autos, and having witnessed the groups fired by World class shooters, at some level the human error error is still the greatest source of inaccuracy.

Semi-Auto... no bolt guns allowed

This is my opinion, but I would say bolt-actions are the simplest and most repeatable firearm platforms, hence giving the most consistency and repeatability which is crucial for achieving the smallest groups. Semi-autos have a lot more moving parts that will not repeat as well round-to-round. They get dirty faster, and are more picky because they need to cycle rounds to function properly. I plan on aquiring a Sako TRG series or the AW series from AI eventually.

That said, semi-automatic firearms have advanced a lot and they're quickly gaining ground in reliability and shrinking their group sizes. The AR rifles appear to be leading the pack on accurized semi-automatics. The M1A's have a loyal following as well.

Personally, I feel the PSG-1 is a fairly old rifle. And there is very little information on it, so its difficult to tell if it lives up to the mystique it has created. I've only handled one briefly so I can't speak to it's actual performance. The same applies to other rare firearms like the Walther WA2000. Rare doesn't mean top performing. If that were so, it's very probable world class competitors would be using these, despite their premium price because accuracy is final and price is secondary when they have gobs of money from their own pockets and sponsors.

I've read good things on the AR-10 from Armalite and the DPMS LR-308. Many people are getting 3/4MOA, even around the .5MOA mark. I have a DPMS LR-308 on order right now and it's going to be a long (but worthwhile) wait. I have heard that the SR-25s are overpriced by about a factor of 2-3x and you can build something similar at less than half the cost from DPMS or Armalite. I briefly handled one at a local show and it was impressive, but didn't seem special enough for the sticker price. You just don't get their cool crest logo and bragging rights of having an actual SR-25.

I suppose its the same animosity felt towards other AR15 rifle "clones" by Colt fans.

What's the purpose of the gun? If hunting, then a semi-auto 308 would be killer in the woods. IF shooting at 1000yd targets from a bench, then I'd look for something else. In either situation, the gun is probably more accurate than most shooters, especially if you are in the field and not shooting from a bench.
