Reply With QuoteWhich bullets are you using ? The manufacturer should have a barrel twist rate recommendation based on the expected MV. You don't mention caliber, but I assume 308 ?
Will a 30" 1 in 12 twist stabilize bullets heavy enough for 600 yard F-class. Found them available for small shank savage in stock and wanted to make sure before ordering. Thanks.

Sorry, yes...308 and was planning on 165 to 175 gr. But was wondering how heavy (or long) could go with a 12" twist...
Since VLD's need the fastest twist to stabilize because of the long pointy nose, if you look here http://www.bergerbullets.com/products/target-bullets/
They show 1:12 being fine up to the 175gr weight (they have a G1 BC of over 0.50, so great for long range). But if you look at the 210's to 230's you need a 1:10 twist rate which for many years was the default twist rate for a 308. You would need to run the wind drift numbers on the 210's to see how much better they are than a 168 or 185. At long range, wind is the killer.
A 1-12 twist will be fine for 150gr to 180gr .30 cal match bullets.
Thanks guys. I might just order the barrel.
I concur I have a 12 twist, and it has stabilized everything I have shot out of it up to 180s anyway.
