My load in the predator is 24.5gr RL=15 behind the 75 amax. with the mag mods. For 2850 fps
Without mag mods go with the 75 bthp


What do you have to do to modify the RAR mags? Is that just a Dremel job or something else?

Also, I corrected the COAL in my post above. The ASC mags allow a 2.316" COAL and my RAR mags will allow 2.260".
