DM11 velocity issues-Need Help!!!

Toler 21 · 09-30-2012, 06:36 PM

Ok my DM11 shoots ropes at about 275-285 fps for about 200-300 shots and then the velocity just drops and maybe shoots in the upper 100s. I rebuilt/cleaned/lubed the bolt twice with brand new o- rings, adjusted the lpr/hpr apropriately, adjusted the dwell, cleaned/lubed the hyper 3. it has a fresh duracell 9 volt along with being at factory settings. I have even tried my NT11s hyper 3 and still the same issue. I use a ninja grey ghost/ medium pressure ninja reg so it is not the tank. Any help????

What is your LPR at? Has this problem only happened with the one new Duracell battery, or has it done this with multiple batteries?

Also Have you tried anyone else's tank?
