Peoblem::: when i start to shoot fast wit my sinlge trigger stock mephy, i start 2 chopp 2 out off 5 balls. not in the chamber , but in the barrel. i checked the paint and thats not it.
OK based on only what you have posted the following seems to be the logical assumption.....
When you shoot "FAST" it breaks paint. I'll assume when you don't shoot fast it does NOT break paint. (you didn't say). If that's the case then it shouldn't be the barrel because it would just break the paint no matter what speed you shoot.
I know you stated the breaks wern't in the chamber but I'm still inclined to believe it's a "CHOPPING" issue rather than a barrel issue. Forgive me for asking but you are using a motorized hopper, aren't you? (you didn't say). CPT hit on another possible prob.... the paint could be a little large for the bore of the barrel. Maybe the first ball isn't getting enough time to squeeeeeeeze out of the way before you fire the second ball during your fast shooting. Check yer paint to barrel match as previously suggested. Last, how old is the paint and what brand. If you bought an off brand & it's kinda old that could be an issue as well.
