I have heard that over cleaning / aggressive cleaning damages barrels also. What you said. I clean after I shoot as I never really know when I'll get out next. My browning looses accuracy at around 50 shots. Wondering if bedding would get my accuracy more consistent. I'll be playing around this weekend as long as the weather holds out. Want to try those 130 grains but don't want to use up my h4350. I will try the imr4350 or imr 7828.
