Re: Barrel twist rate help
Proper barrel twist has more to do with bullet length then weight. The longer the bullet the faster the twist.
Certain twist are needed to stabilize the bullet.
Having said that, longer bullets normally means more weight.
To make a long story short, 1:10 twist in an '06 will handle anything up to 220 gr bullets.
Rule of thumb, a fast twist will shoot light (short bullets) better the a slow twist will shoot heavy (long) bullets.
The exception to that rule is super light, thin jacketed bullets for varmints. If pushed to fast in fast twist barrel the may come apart in flight.
Most gun manufactures take into account shooters/hunters will shoot a variety of bullets, therefore the sell their rifles with twist that will work for a variety of bullets.
So to answer your question your 1:10 twist will work fine on elk/moose size animals with any normal hunting bullets for those animals.
