I got a 788 6mm for $350 from a pawn shop 2years ago. Was about to sell it because it was shooting 3" groups, then I remembered it had been a year ago since I shot it and didn't clean the barrel after a lot of shooting, kinda forgot about it. So I gave the barrel a good cleaning and, presto, 3/4"groups now.
I had 2 new ones, 22-250 and 6mm Rem when they first came out, very accurate rifles, better than my Rem 700, but broke the bolt handle off the 22-250 trying to eject a handload and so I sold them. Regretted it ever since................only dislike are they are kinda heavy, like to find a synthetic stock for my 6mm............
