    Twist Rate for .308

    Hi all, I purchased an SPS Tactical with a 20" 1 in 12 twist a few months ago and while I love the gun so far it seems like every internet forum is completely swayed to the AAC-SD with the 1 in 10 twist. When I purchased it, I was under the impression that the 1 in 12 was the better of the...

    .308- 1:10 twist rate- are 150gr bullets hopeless?

    Getting my 308 rebarreled its an 18.5" 1:10 twist barrel. Most of my bullets are 150gr- what are the effects on twist rate. Is it a definite thing that 150gr bullets will suck as I hear these 1:10 are best with the heavier pills

    I need a starting point for loads for an AR-15. It has a 20inch barrel with a 1-9 twist. I will be using this for shots out to 600 and do not want to single load. Yes I have read the .223 reloading section.

    Range Report Twist Rates

    It's been a while since I've posted, but the last few times I saw the issue of barrel twist rate come up there never seems to be included a discussion about atmospheric conditions as effecting bullet stability. But the fact is that whether a given bullet is stable upon exiting the barrel...

    I have just acquired a 308 Win with a 18" 1-10" twist barrel with very few shots down the tube. I have been asked to set the rifle up shoot up to 1,000 yards. I shoot a variety of 6.5 mm rifles out to 1,000 yards but do not have a lot of experience with the .308 Win so please excuse my...

    .243 twist ? Rem SPS Varmint

    I'm pondering the Remington SPS Varmint in a .243, which comes with a 26" 9 1/8" twist barrel. It seems like 1-8 is the way to go, but would the Rem factory barrel likely be O.K. with the 105/107gr range of bullets? Down the road I could always have a new barrel put on, but I'm thinking of the...

    Range Report understanding bullet weights and barrel twist

    When you are working with barrel twist rates, the heavier the projectile, the faster the twist you need. This much I understand. Now is where it gets murky. If you have two guns chambered for different calibers that use barrels with the same twist rate, Why does the twist rate not support the...

    185gr and 1/12 twist?

    Hello, I have a thousand or so Lapua 185gr D46 bullets. I was wondering if these would be accurate through a 24" 1/12 twist L-W barrel? I know longer bullets like faster twists and these things are pretty long. Here's a sample pic:

    Twist Q

    Okay guys, I'm going to add a .243 Win bbl to my Surgeon build. I've been told that 1/8 twist, 1/7.5 twist and a 1/7.8 twist is "ideal", only one answer can be accurate. Going to shoot the DTAC's exclusively, what twist do I want and why? Cheers, Rath

    Gunsmithing Twist rate for 110 gr 308?

    1 in 12? 1 in 14? Got a bunch of 110 gr Hornady TAP available. The faster twist barrels don't like it much. They are much happier with the 168 gr.

    Gain twist

    Ordering a gain twist barrel for the 338. Where to start and finish at is the discussion. I'm thinking 10 twist to start and 6 twist at the end. Should work well with the heavier long for caliber, lathe turned bullets. What are you guys thinking?

    6x47L what twist would you use??

    I may be chambering a 6x47L here in my next project. I need a rifle to hunt coyotes with and hopefully a pig hunt as well. I think i will try a 6x47L but i am undecided on what twist to use.
