223rem is going to be Benchmark. I have tried H322 and H335 and cant get the accuracy I get from Benchmark. 9mm-I tried HP38 and BE86 and while I like the accuracy of BE86 I think its got too much punch for me. 44mag-I have only ever tried IMR 4227 and stuck with it cause its accurate. 38spl-I tried BE86 and HP38 and HP38 won. 45-70-Only ever tried IMR 4198 and like the accuracy and velocity but may try something else soon.
