Ok so I ordered a .284 diameter barrel from Krieger with a 1:9 twist wanting to do a 7mm-08AI build but know I'm thinking .284Win looks just as good. My reason for the 7mm-08 was I have seen one that is pushing 120gr NBT's at 3400fps with 23 or 24" barrel which I think would be a great varmint round, my question I guess is which would you choose? All I have really found on the .284 pushing anything very fast is the 180's which I don't think I could stabilize.
