Well I've been talking to scope eye about the 22-250 since I started this thread and I've yet to hear one negative on 22-250....I'm just going to look at a single stage press this weekend and then I'll roll my own 22-250 cartridges. I've read so much on calibers in the last 2 weeks I can't process it all, I know 22-250 is different than 22-250 AI but from what I read you use a regular 22-250 cartridge to form the 22-250 AI by shooting it? is that correct. Assuming you have 22-250 AI barrel.
