Default Anyone Reloading a short Barreled 308

I have a Remington Model 7 with a 20" Broughton 1:12, 5C. barrel. I have been trying to get 130 and 150 Barnes TTS to shoot sub .5 MOA. So far the only bullet I have acheived this with is a Nosler 150 Accubond and Swift Scirocco. This rifle has been timed and trued. It is riding on two pillar beds and the lug is glassed in. I have switched the scopes and bases around several times.

Just gurious on what your expectations might be.

I am just guessing that you have met the limitations of the rifle. I mean, a half inch moa at 100 yards with light bullets sounds pretty good to me.

Nate: I shoot the 130 Barnes bullet out of my Encore pistol - 15" bbl. It has a 1-10 twist. It'll shoot one inch if I cooperate. I don't expect more from any rifle or pistol. When I get to one inch (if I get to one inch), I come off the bench and shoot from field positions.
There's always the possibility that that bullet won't shoot what you want it to in that gun.

I would say start experimenting with different powders and loads, if you can shoot .5" groups with 150gr noslers and Swifts, you should be able to get it with the Barnes, you just probably havent found the powder combination for the Barnes. Myself, my load for the 300win mag with the Nosler BTs was always IMR 4350, when I switched to the Barnes TSX my groups opened up to 1.75" from .5, after trying several different powders and loads, I got back to .5 with RL22.

Smile Barnes Bullets...

perform best at higher weights for the caliber. Start with 168 gr then try 180 gr. I think will be able to get clover leaf groups with the 180's if you can't call Ty at Barnes he is great!

ive got a remington M700 mountain rifle in 308 has a 20" barrel but with a 1 in 10 twist. totally stock rifle no bedding with a toothpick barrel that isnt even free floated. But it shoots excellent my current load for it is a 165 grain SST over 45.5 grains RL-15 in remington brass and magtech primers set a COL of 2.800" the load prints real tight! Im not real sure how to measure groups but all holes of 5 shots touch and could fit under a nickle.

Denoting a 2.800" COAL,less throat geometry is moot...though 308's Remmies are long throated like Linda Lovelace,so the best move is always to crowd mag confines to minimize their leap to the lands.

As per he initial query and assuming a modicum of thought,the throat had better been cut with far more thought than that or all quickly becomes moot. A barrel can be no better than it's throat or chamber.

Though admittedly,'15 is always the ticket in the 308...................

I agree with one post, try a heavier bullet. My Browning BLR .308 loves the 180 grain vs 150. Have not found a powder/bullet combo in 150 grain that works. Bump up to 165 and especially 180s and I get results like your talking about and my rifle is stock, lever action and short barrel!

The .308 was developed around the 150 grain bullet weight but as time went on it became apparent that the optumum bullet weight was 168 gr. for best accuracy. I would also start by seating the bullet .050 off the lands as this is what TY at Barnes recommends. Then move it in or out by .005 to find tune the load. I happen to shoot the TTSX in the 168 gr weight and have found as many do, that Varget works very well with just about any bullet in that weight range and try to keep the velocity between 2500 & 2600 FPS. But by the same token if you were able to get the Scirocco & Nosler bullets to fly true with what your using for components, it maybe as simple as moving the seating of the Barnes a little to tune it in. I would give that a go before anything.
