I recently bought my better half her first rifle, a 10/22 Sporter. Bear was thrilled, and so was I. But, it shot like crap. Mostly due to a very poor trigger. Not something that I wanted to teach her with.
Anyways... After a bit of frustration I talked with bear about it, and he sent me a trigger group. To say that the difference was fantastic is an understatement.
With standard Mini Mag target Plinker ammo it is shooting dime size groups at fifty yards. At least when I do my part!
He does the same things with 870's and next month he will have one of those to work his magic on!
