Re: 22-250 build help
I'm building a 22-250 now. You need to make a choice: Do you want to build a varmint rifle or a long range rifle. Both are very different.
Varmint - build using a 1 in 14" twist barrel, 26" long. That's probably the most efficient.
Long range - build using a 1 in 7" twist, 22-250AI will a 28" barrel. You can use some slower powder. Note that it has not been proven to me that a 26" barrel will not work just as well.
