[QUOTE="Shumba, post: 646729, member: 12337"] I have had a few 243 Catbirds. The Catbird is a 270 case necked to 243 and improved. My opinion is that you are not going to gain much in that short of a barrel. As Bart B said they are hard on barrels as well. Not nearly as bad as his expectation of 500 rounds but if you don't have a barrel just for fire forming brass it's not the best choice. Barrel life for top accuracy is in the 1200 round range depending on how you shot it, i have one with 1900 rounds and it will still shoot 1/2 MOA. Accuracy is typically great. Making brass from 30-06 cases is not a simple process either. I use a form die with 270 cases to step the neck down and make a false shoulder. With the 30-06 it will be more involved. I have had 4 catbirds and 26" is the shortest barrel I have put on one, 28" is much better. Hope this helps. [/QUOTE]
