Yes, well kinda, 2 out of 3 loads I've tried with 55gr blitzkings that shot 1" in my Stevens .243. I'm still working on a load for the 80gr rem PSP. When I shot to work up to max, they weren't grouped real well at all but I'll blame that one on the wind and try a couple of different loads here in the next week or so. Your definition of "any luck" may be different but that is good enough for me. It is the only powder I've tried because I also use it for my 30/06. If it continues to work this well, I won't bother to try any others. Ball powders with magnum primers are predictible and I like to keep it simple.
