I am going on my first ever prairie dog hunt this spring in south Dakota.I want to build a switch barrel rifle for the trip and this is what i am thinking i need. I just bought a new stiller P-1000 action. These actions are big. the are 1.550 around and longer than the predator actions they make. I want my rifle to be big and heavy so i can see my hits or misses. I am going to do a 6mm and a 22cal. probably a 6BR and a 22br or possibly a 22-250AI. I want my barrels big as well. I am thinking 1.250. Midway Usa has unturned 22 and 6mm barrel blanks for 130 bucks each. these are chrome moly barrels. What i dont know is if these unturned barrels have been stress relieved or if that will need to be done. Can i just chamber these unturned barrels up and shoot them? I know these barrels will foul more than a lapped stainless so i was wondering if there was anything i could do to them before i start shooting them? I figured these cheep barrels would be the way to go for all the shooting we will hopefully do. Can anyone add or think about anything i need to do or is this all a bad idea? The 22cal barrel will be a 12 twist and i will shoot 55gr v-max, not sure about the 6mm yet. Thanks Lee
