1-10" is more common to handle the more streamline heavier weights. While I haven't run a program on the issue, I would say 1-12" is more appropriate. That said, I also have been a proponenet, of when in doubt a tad faster is better than a tad slower. If you are over stabilized slightly, you may find to things. At shorter range, it takes time for the bullet to "sleep", therefore you may not see it's real accuracy potenial untill 100-200 yds. Then again at extreme range their are other problems, But these range are way out there beyond the norm of hunting.
Personally, in a rifle barrel, I would go with the 12" twist if I had no plans of shooting anything over a 200 gr. VLD.
For most on here there is a dream trip floating up around in their heads but there is a question of how to pay for it. This has been a problem for all hunters that wish for that elusive moose, bear, goat, sheep, elk, deer, or any other hunt where you are required to hire a guide or you choose to hire one for that hunt of a lifetime.
First off I am not a financial planner I am just a hunter that learned a long time ago that even with a great job there are going to be some...
