dm4 help please--inconsistent velocity
I am shooting pretty well with my DM4. I don't get first shot drop off any more or anything like that.
When I chrono it, the velocities are pretty inconsistent. It'll be like 260, 265, 230, 245, 264, 235, 245, 250, 260,
etc. So it'll drop down to even 235 when I thought I had it set at 270fps...
So, what to do?
1). I heard it could be my LPR...should I turn it OUT or IN?
2). I also heard it could just be the imperfections of the ball.... hmm. I kinda underbore the balls. .285 barrel back. could this be it?
3). Has nothing to do with Dwell right?
