According to the ammo oracle, the best all around twist for a .223 round is the 1:9. How come alot of the bolt action hunting rifles have a 1:12? Is there a hunting related reason or is Remington and Browning behind the times?

I would venture to say a little of both. I suppose most of the people buying .223 bolt actions are getting them for use as varmint rifles. With the choices in varmint ammo (usually 40-55 gr), the 1/12 will suffice. But I would like to see them move to 1/9 as the standard twist at least. Remington already does this with their .223 LTR's. -Charging Handle

I'd like to see 1/7 twist for use of the long bullets. You're right though Charge. Varmint rifles are used for shooting shorter light bullets, and 1/12 twist works good all the way up to 55 grain bullets.

FYI, Savage .223 bolt guns have 1 in 9. I would agree that 1 in 12 is for shooting lighter varmint bullets, but my 1 in 9 does really well with 45 gr up to 69 (from what I've tested).

I have a 45 grain varmint load that i cannot shoot in the 1/9" barrels; it explodes in midair about 25 feet in front of the muzzle. Short, fast bullets need a 1/12" twist.

Most bolt guns in .223 are made for shooting varmints, not necessarily for shooting SS-109 and heavy match bullets. For bullet weights 55 grains and under, 1:12" is just fine, and 55 grains and under is what most people use for shooting varmints with .22 cal centerfires.

My Savage 110fple shoots Hornady 75gr pretty well.I think that is the limit for a 1:9 twist

I was using the Walmart 45gr stuff, it's great. Must be bullet construction, I've read in Reloading manuals that some really thin jacketed bullets will not handle faster twist rates. I agree with all above 1 in 12 is all that is needed for a small varmint bolt gun. I love the extra versitality of the 1 in 9 though.

I prefer the versatility of a 1/9" also, but it doesn't do *everything*, like the light/fast rounds. My load is a little (lot) faster than the Wal-Mart ammo is likely to be; it took a lot of development to get a load that was safe but fast. It is effective on light animals and gives me that little edge in speed. I *do* wish NEF would give an option in twist rates on their barrels, though. Larry

I have a Savage 12FV that shoots sub-.5MOA with Black Hills 75 and 77 grain moly ammo. It really might shoot better than that, but that's the best I can do from a bipod with a rear bag.
