H335 and Remington 7 1/2 Benchrest primers produce the best accuracy in my CZ 527 .223 with bullets under 55 grains. Over 55 grains H4895 with the 7 1/2 primers does slightly better.

I never use magnum primers with any non-magnum rifle load with exception of long action .270 and .30-06 loads with IMR 4350. It appears to produce a bit more accuracy but the POI changes a bit.
