I have the 22-250 1:12". I love the gun, but I'm goin' to get the 6NormaBR as soon as I get the cash. This sounds like the all-around varmint gun. I did a lot of research on it in the past few months, and if I had it to do again, I'd buy the 6BR. 22-250 factory ammo is gonna be cheaper, but... If you handload...
Here's a review for the 12LRPV: Savage model 12 long range precision
Check out 6mmbr.com also, here's the link for that: http://www.6mmbr.com/6mmbr.html
From the tone of the posts, buy the 6BR lol.
Good luck, and keep us posted.
