Gents: What twist will enable one to shoot 180-220 grain bullets in a 30 06? Does barrel length affect this? thanks. | ||

Go with 1-10 twist. Barrel length has nothing to do with it. Remember, forgivness is easier to get than permission. | |||

12" twist will be the slowest to use. Yes barrel lenght does effect this. You will want a 22" minimum, preferable a 24-26". Velocity determines RPM which means stability so you want to have enough velocity to stabilize the bullets over the distance you are shooting them. If you have a shorter barrel then the standard 10" twist is the way to go. Larry Gibson | |||

I had two 30-06 build with 1/11 twist barrel used in both rifles one barrel was from Lilja 3 groove other from Bartlein 5r. I have to say shooting the same load the Lilja barrel was faster but it had 2" more barrel. I then had the lija barrel cut to same length as the Bartlein then it became alittle slower. Never know. I shoot 180's in both 30-06 haven't tried 200gr but think they would work OK. VFW | |||

A 1-10" twist has worked well for all bullet weights normally used in the 30-06 for over 100 years and still remains the best choice. 220 grain bullets are traditional, as they were in the Krag before, and 99% of the rifles firing them had a 1-10" twist. IIRC only a few -06s were different, like Remington's varmint model and Husqvarna for example, where a 1-12" twist was used. | |||

Tikka/Sako uses 1/11 twist for all their 30 caliber rifles. Best thing if your building something call barrel guy your going to use and he give you what bullets work. VFW | |||

Use enough twist and one does not have to wring the last FPS out to stabilize the bullet 1 in 10 twist is the standard and works extremely well _____________________________________________________ A 9mm may expand to a larger diameter, but a 45 ain't going to shrink Men occasionally stumble over the truth, but most of them pick themselves up and hurry off as if nothing had happened. - Winston Churchill | |||
