I have lurked here a while and wanted to say hi and ask for some suggestions. I have a handi rifle with two barrels - a 243 and a 308. They shoot well but are very sensitive to how tight the screw on the lug is. I very rarely shoot the 243 barrel as it is hard to seat bullets close to the lands and it has been a little more problematic to get to shoot well. I am thinking I may never hunt with either barrel as I won't have the degree of confidence in them as I have with several bolt rifles and lever rifles. My son and I like to tinker and have made a 257 Roberts on a commercial bolt action, which was a lot of fun to do together. The Handi rifle is fun to shoot at the range, but if that is all I will do with it, I am starting to think that instead of the 308 and 243 I should instead get a barrel to tinker with that might be fun to shoot at the range. I have been thinking along the lines of rechambering the 243 win barrel to 6 Rem AI, but I am generally not a big fan of AI cartridges. I have also thought about getting a 30-30 barrel to shoot as is, or to change to 307 win or 30-40 krag. I know that doesn't make sense as I have a 308, but again I am just wanting something a little different and something my son and I can do together. I have also been thinking about the 38-55 but the recent thread on that makes me hesitate. Anyway, sorry to babble but I would like to hear about any success or failures anyone has had taking a 243 barrel with a long throat and making it a 6 Rem AI or if anyone can describe the level of difficulty on working with the extractor on a 30-30 barrel to get it to work on a 30-40 case. Thanks!
