Velocity dilema, 280 or 297?
I recently made an awesome sniper pump with CCM, AKA, MacDev and FBM parts. Adjusting the velocity I can set my IVG at 2 threads in with the reg set right in the middle to get a nice and clean 280 FPS with very little kick. Alternately, I can set the IVG at 5 threads in and the reg about 3/4 up and get 297. At 297 it shoots a little rougher, you can feel the hammer slam into the valve and hear the valve and spring rattle after a shot.
So I don't really mind the extra kick, but I am a little concerned that I may be causing undue wear on my marker for a few extra FPS. What do you guys think?
