I just came back from sighting in a new LR-308, 24" SS Barrel.

Although we didn't measure the groups, they were 'not large' at 100 yards.

I was not impressed .... or maybe unfavorably impressed by the gritty, long trigger pull. It also has the famous 'Slinky Spring' sound as the trigger slowly creeps.

With a bit of trigger work, I think this thing will group tight.

But, boy does this gun shoot well.

good deal Ron. I got a 6.5 Creedmoor built on the same DPMS platform, I've got some brass and dies, but have some factory Hornady ammo I want to go out and try, but probably won't be this week, have other guns to shoot first.

Trigger is important, this one has RRA 2 Stage with JP Springs, which is pretty light, I normally don't put in JP springs, but came that way so i'll try it out.

Those 24" barrels are heavy, mine is full fluted and still heavy as heck...

Yes, I got the fluted barrel also.

I've got a batch of trigger springs ordered from Wolff and will use the instructions from the link you sent to 'play' with the trigger. On a $1000+ gun, it seems like a good trigger would be standard, not optional.

I have the DPMS AP4 LR-308 and it's my best grouping rifle I own right now. Not long ago, I had to replace the riser on the rifle. Well, went to the range to see how far off it was. Made the first 2 shots, it was a bit high. I dialed the scope down and the second 2 shots were, well, satisfactory. As for the trigger, I'm agree with you guys; for the amount you pay for that rifle and extra $150 trigger would be easy to add in without noticing to much of a cost increase. I still need to change mine out.
BTW: If you have any issues, get ahold of DPMS directly. They are very helpful on making things right.

Here's the pic of what I described (100 yds) with factory ammo (Federal 165 Trophy Bond).

And to add, this was one of my first serious rifles. Which I did some what of a "break in cleaning" method. Take a shot, clean, take another few shots, clean, etc... I'm not sure how critical it is to do that, but I guess it can't hurt...

Good Luck!

Drop in a Wilson Combat TTU and it will fix that trigger problem in about 5 min...................several variations to choose from, I've got a light two stage in my DPMS 308. Also took max weight off my bbl and cut it to 14.7" and it's still a heavy gun.................. We got a 458 SOCOM down to 8# 2oz loaded with 8rds and a Trijicon 3-9x40 installed, a VERY handy package that hits really hard and recoil is no worse than the heavy DPMS 308. The heavy bolt carrier assembly in the 308s just plain make them kick. There is a HUGE difference in recoil between the DPMS 308 and a Browning Short Track BAR in 308, it's like comparing a 243 bolt gun to a 30-06 bolt gun. For hunting the Browning BAR is the way to go if you want a semi-auto and a cartridge too big to fit in a AR-15 platform.

32 years and 2 days ago ( March 2, 1980 ) I fired the second group of five shots
from a new Shilen barrel in .280 Remington. It grouped .571 for 5 shots.
Never heard of a barrel break in procedure back in those days....
I still have the target.

I'm not sure but maybe the cleaning supply folks invented the procedure ....

For some reason I didn't think the recoil was more than just noticeable. Of course, I've owner quite a few large bore rifles and don't mind even 'elephant guns' except from a bench.

It is nice to know the .458 SOCOM has less recoil. I have had one on order from Rock River since last year. Will probably employ a low power scope or 'red dot' type sight, it depends on how bad the squirrels are at the time it arrives.

But Burt, you are the Chuck Norris of guns and ammo, they fear to stray when you're pulling the trigger... j/k Laughing Seriously though, I've heard from several others as well say that the "break in cleaning" is a bunch of hog wash.

Bill - I agree, the LR-308 is very heavy for stalking. I remember walking 700 acres with it, will never make that mistake again. When I hunt a baited area, having a heavier rifle is not much of a factor for me. Thanks for the trigger info., I'll go check out your website...
Here soon I'll be getting a large bore AR Upper. Which I do have a question, after getting a large bore upper, do you recommend getting a heavy buffer or will the factory buffer be ok?

It's very interesting that you should mention the Short-trac. About two years ago, I was in a Gander Mountain and handled a Short-trac for the first time. To be perfectly honest, I'm not much into autoloaders these days (although about six months ago I bought my first black rifle since I sold my pre-ban Valmet M76 that I got in 1988), but I really liked how the Short-trac felt ergonomically. About a year later, I ran into a deal on a 7mm WSM Short-trac that was too good to refuse, and so I took the plunge.

All in all, I'm very happy with it, and I too find the recoil to be modest, for the caliber. The trigger is mediocre of course, but not terrible, and the rifle will shoot into about 2.5 - 3.0 inches at 200 yards, with a target scope, which is pretty good considering the light weight and fine handling qualities of the firearm. I've yet to actually shoot any game with the rifle, a deficiency I hope to address some time this year.

After reading the latest about the new CFE 223 powder Hodgdon came out with,
it will be even more hogwash. Bore scope photos showed virtually no metal
fouling build up after 100 rounds even.
( CFE = Copper Fouling Eraser ) This powder is usable in the .308 Winchester, so....

Burt,

Do they have a TSA (TSA = Target Seeking Additive) for those calibers? Sure help a lot on a dark night with lots of hogs.

You know about the laser guided bullet they developed, right ?
I doubt it will ever be seen for public use though.

Spring and buffer weight depends on the gas port size. I have mine set-up with adj gas blocks, so I adjust them to just lock open with a loose grip using std buffer and spring. RRA puts huge gas ports in their 458 bbls so you probably need a heavy spring and buffer.

good thing about the 458 rifle is it comes with 3 different spring weights, so it comes down to what load you are using. I recently installed an adjustable gas block on my .264, nice for tuning purposes like Bill said

Was visiting my retired Navy SEAL buddy when a fellow asked his favorite weapon.

"Radio, call in an air strike", he dryly replied.
