Thanks for the reply and the tips. The last time I went to the range I used a Lohman Sight Vise, similar to what you describe. You clamp the rifle stock in the padded jaws and it has an elevation adjustment at the rear . Then you move the vise side to side to align the gun horizontaly. Pretty stable platform. When I referred to "reticle adjustments" I'm talking about elevation and windage for the crosshairs, which as a pair, are the reticles. I probably should have just called them crosshairs to avoid confusion. I think the adjustment you're referring to is the reticle focus adjustment. There was a little crosswind but the range is heavily tree'd on both sides. Since shooting last I cleaned the barrel three times with Hoppes Copper Solvent and am still getting dirty patches. I'll clean it again tonight. I also readjusted the BOSS to the setting for 225g bullets, it was on the setting for 250g bullets as that was what I used last year. I'll try it again this weekend. I am a fair shooter. I can't claim MOA groups at 100 yds everytime I shoot. I can definitely shoot better than the last couple of outings with this gun. We'll see if the barrel fouling was hurting it bad or not.
