I was shooting 460 grain no excuses. Using triple 7 fffg. There was a " stickiness in the barrel" Had to really work em down the tube. Then they got easier to pass. They were grouping awfully. Switched to a power belt 395 grain. Shot two they grouped a little under 2.5 inches at 100 yards. Started to load number 3 and noticed the bulge...about 7 inches from the muzzel?
