To the OP, you are putting a severe handicap on yourself & probably your rifle by not reloading, my thinking is if you can drop a couple large on a GAP why not a few hundred on reloading equipment? I'm not trying to be mean, just curious.
Give the HSM a try it can't hurt, at very least you will get some trigger time, I don't know jack about the Bergers so I'll leave that to someone else.
Some of the custom ammo makers used to offer a "sample pack" if you will, a box of different loads to present the ability to find what your rifle likes best. I'm sure someone still does this, it might be worth your time to look into.
