You should be safe using any same weight bullet\’s recipes other than plated and cast lead bullets. I\’m trying out the 124 gr NUKEs for the 1st time when I get them. I\’ll primarily be using them in 9mm PCCs and my MP-5 Clone. Hollow points are harder to feed in unramped barrels which most 9mm PCCs are (unramped), accept for my CZ Scorpion which eats anything I feed it.
