I'm starting some load development for .222Rem using IMR4227 and Federal 200 Magnum Small Pistol Primers. Starting load is 14.0gr. under an Sie. 1385 40gr. HP and working up to 14.8gr. in 5 steps. Anyone loaded this combination before? If so how were your results? Going to try to get to the range Tuesday or Wednesday for chronograph and accuracy for the first load and I'll post what I come up with.
