.....
Why such a slow twist instead of going with a 1:10?
That's a factory barrel and the standard twist (the only one available...) is 1 in 11". No choice there.
.....The 220's are made with people who are single loading and have long throats in mind.
I am single loading (no magazine).
On the paper the 200's looked like the heaviest to be stabilized by that TR and would probably do pretty much the same as the 212, for my own use......If I had to guess I'd say with that barrel the 200gr or lighter will work better for you than the 212's but you never know till you start working up loads.
.....Hornady is real good about answering the phone and helping people out so you might just want to give them a call for twist rate suggestions.
I am gonna e-mail them and see what their thoughts are...
