Hello ladies and gents all I can say is what a great site. I was looking for some info on switching calibers on a model 11 I picked up really cheep. I paid 400 and that was with a bushnell 10x, choate stock, timmey trigger, and a harris bipod. I have a few rifles in .223 so I want to switch this one to .308. I know where to get a barrel but where should I buy a bolt or just the head from and what can I do with the blind mag to fit a .308 round? Any help would be greatly appreciated.
