I have a Wolf and an Optima, and spent several range sessions finding powder/bullet combinations for each gun. Last range session the Wolf seemed to love 90gr of B, H209 and the Scorpion PT 260gr in a crush rib. At 100 yards my last 5-6 shots were in a 2-3" group, 1" high. I was extremely pleased. With the Optima, 100gr BH209 and Barnes TEZ 290's were shooting equally as well. I left thoroughly pleased. Fast forward a few days and I decided to stop by the range again and just check everything and fire a few more shots. Now both guns were all over the place. High, right, 5-6" groups at 100yds. What the heck is going on. This is off of a lead sled too. Both guns were cleaned meticulously after every range session. Exact same components used every time.
Am I missing something? Everything is snug, nothing loose anywhere at all. Anything like the forearm screw matter, as in how loose or tight it is? Sounds like a stupid question, but I can't think of anything else. What would cause my groups to open up like that?
