I have never shot the 52's.. But lots and lots of 55's. I have had stellar results with AA2015, W748, Benchmark, N135 and H4895.
I had 2 rifles in the past that would not shoot, despite using all the favorites. I fed them AA2015 and magic appeared before my eyes.
My most accurate rifle shoots 55 Nosler BT's with 26.7-26.9 grains of W748. I am not changing a thing or screwing around with it.
H4895 just works. It goes nuts with CCI #41's. +50 - +100 fps faster than with other primers. Be careful!
I doubt N135 is the best powder for those light bullets, but it sure works great and goes fast with 55's
Benchmark.... purple container, awesome velocity. Everybody's dream.
