Praharin:
To answer you, I wasn't going to use the same crown or action. I am not quite that much of a newb. I am however, concerned about being able to use a heavier bullet.
I'm frustrated that Remington used a "varmint" rifle platform with a 1/12 twist when using "factory" ammo, the effective range has been only out to 200 yards (for DRT action).
The sucker is 15 pounds with all the gear, and it's not a brush gun... when I varmint hunt, I'm not moving around, mind you, but if I'm in a box blind, it's a hard gun to manuever in and out. So maybe I'll just have a smith cut 5-6 inches off, and place a crown and thread on it, so I can put the can on it that I want. Effectively making the rifle again a 26" Barrel with the can on it, but without it being illegal (ya know... whole short barrel rifle thing!).
