buddy got a .243 in CVA.
Its acting really weird, after cleaning it will shoot so high its off the paper, next round will be come down 6" then next round another 2 next round maybe 2" then it will settle in on or around the 5th shot.
Any ideas.
The way I clean is patch solvent , then dry patches, then wet patch copper remover, then wet brush copper remover 10 strokes, then dry patches, then wet patch solvent, then dry patches, then wet oil patch, then dry patches.

My vanguard will shoot damn near on the money on first shot cleaning this way, im talking 3/4" off the next 3.
