Change your powders and/or bullet weights. I have a finnicky gun that will NOT shoot any 140g bullet. I tried Varget, RL15, RL17, I4350, I4320,I4064 powders, 120, 130, and 150g bullets. Found it likes Varget and 120's, Varget and 150's, and 4064 and 130's. You just have to find the right combo that YOUR gun likes. Might be cheaper to buy bullets than different powders, but if you have lots of bullets left might try some of the powders I've tried, or some others that the fine folks here on the fire will I am sure suggest.
