Don't know where you were told you had to shoot "neutered" loads. I've had my Delta for over 30 years and i've only shot regular loads in it and it's still hanging in there. Granted, I don't shoot extensively with it. I use it, not abuse it. I even have some heavy loads for my .45 ACP. If I want lighter loads, I'll use my .40 Short&Weak or my 9mm. Realisticly, you only need max loads for hunting or self defense. Practice with reduced loads and use full power for tune ups prior for hunting. Much more comfortable and your fire arm will last longer. Also, I don't like polygonal rifling. I only use factory jacketed ammo for self defense because prosecutors in my state consider hand loads pre meditated assault. Go figure! I feel that cast bullets do not perform well in polygonal rifling. I shoot cast bullets almost exclusively in all my center fire auto loaders except for my .22 TCM and my self defense loads. I agree with some prior people in this forum. Shoot every 10mm you can find, keep the one you like and get rid of rest. Personally, if i'm going to use a handgun for big game, I'll use my .357, 41 Mag, 44 Mag, or .45 Colt revolvers. If I use my Contender, I'll use my .30 or .357 Herrett, 7 TCU, or .357 Max. My XP 100 7mm BR is no slouch either. I'll carry my 10 mm for a back up while hunting, but it is not my preferred big game hunting handgun.
