The long relief scope is a good suggestion. I started him with a slingshot of course, then a BB gun, then a 22. When he started in with a 22-250 he thought he had the centerfire world conquered, especially when he started hitting steel at 400yds..., guess not.
Problem is he's a lefty, so I wanted him to love the Savage99 with a thumb safety as his deer rifle. He didn't like it, so we went to the Savage 110L in 30-06 which matched his 22-250 for fit and feel.
He's a full-grown 5-10" young man, the Savages fit him as well as any factory LH rifle with <14" LOP. I think my next tactic will be going out after woodchucks with the 22-250 and show him a couple 150yd deerfield shots, that he "needs" the 30-06 for.
I really appreciate all the help and suggestions. The answer to this sort of inquiry is always pretty basic..., more trigger time.
