I went with the Elmer Keith rubber washer trick between the forearm and barrel. It's pinch in there and I moved it a 1/4" at a time until it reached its harmonic happy "sweet spot" and then just cinched it in place. I don't know how fool proof it is but I can shoot under moa with both the 115 tsx and the 115 Bergers. So I have a good close range 0 to 300 yd bullet in monometal and the long range 300 to 1000 Bergers. Point of impact is only 1 inch higher with the Barnes but windage is good. I did a cold bore shot at 200 last Saturday just to double check zero and it did this. I'm shooting the bad oem trigger and a VX R 4-12x40 Firedot scope. Nothing too fancy. She just shoots.
