highpower223308 twist rates
been looking at several remington rifles in 308 win. I want a true tactical rifle, one to reach out and touch something long range. I reload and and long range accuracy is my main objective. looking at the stock remington rifles with twist rates of 11.25,11.5, and 12. Can anyone suggest what is best for long range, and at what bullet wt. thanks

okie johnBarrelmakers have charts with twist rates and bullet weights, but they only indicate potential. You'll have to buy a rifle and shoot it to see if any of it is correct for THAT rifle and THAT ammo. And that's a lot more fun than overthinking the problem.
As for other sources of information, check with long-range match shooters. NRA High Power shooters can help a lot. Guys who shoot Palma know how to shoot in the wind, but they're restricted to a 155-gr. bullet by the rules of the game. F-Class shooters have far fewer rules, so they can help as well.
Off the top of my head, I'd use heavier bullets because they buck the wind better, and that means a faster twist. The ability to shoot well in the wind separates the men from the boys at long range.
Good Luck,
Okie John

Jay GorskiI've got an article in one of my Rifleshooter mags where they're shooting at 1000yds. The rifle being used is a stock Rem. VLS,(though I believe they floated the barrel), the bullet is the 175Matchking, twist in the VLS is a 12 twist. Accuracy was 1/2moa out to 1000yds. Hope that answers your question. Jay

vapodogI'd make it a 1-10" twist.

Cal SibleyI have a Browning Micro-medallion in .308Win. It has a 1 in 12" twist and does not do well with the heavier 180gr. bullets. In fact it doesn't always do well with the 168gr. HPBT. Of course how well a bullet will shoot can often be related to bullet type and configuration. It's not just merely weight. Just one mans opinion. Best wishes.

buckshotIf I were in the market for 7.62, I'd go for the 1-10 twist. It has worked for a century in .30-06, and it will work in .308 for all of the same reasons. If it doesn't overstabilize light bullets traveling at 30-06 velocities, it won't do it in the 308 either.
Secondly, 1-12 works up to 175 grains as a general rule, but why limit yourself? Anything a 1-12 twist can do, a 1-10 will do better. Besides, Colt, J.C. Higgins, M-S, Marlin, and Remington (in their 722,740,742,760,700,40XB,788,660,600) made rifles in 7.62/308 with a 1-10 twist.
Last, the 7.62/308 hasn't the case capacity for heavy for calibre bullets, so no need to go with a twist faster then 1-10 either.
