I shot my single shot homemade 50 this week and I'm alittle disappointed. I've heard the api bullets are not to accurate. I picked the barrel up as a 30" chambered blank. I checked the freebore and it has alot (I think) a 750 a-max is in the case about 1/4" to touch the lands. Should I try the a=max's first or just get a reamer and set it back. I hate to throw money down range and not know the problem! Can any one help?
