Hey Mas - thanks for all the good info you share with us folks. Yesterday, I noticed in a catalog a brand of ammo called C.O.P. (Copper Only Projectile). I normally carry the CorBon DPX ammo, but as I'msure you know-it's very expensive. THe C.O.P. ammo in the .45 acp 185 gr loading was almost exactly one-half the price of the DPX brand. Have you gotten any feedback on this brand of ammo? Have you personally tried it? I was thinking of using it for practice, sighting, etc., and saving the DPX for actual carry. . . Have you had any experieince of heard anything about this brand of ammunition? Thanks!
