When testing I was looking for a load for USPSA something about 128 PF.
I did not have a chance to load ladders for everything but my target vel is in a narrow range-> 1020-1050 FPS.
Some of these were loaded before leaving for the range Sunday morning, more tests to be done later.
(also it’s not much fun testing when it’s over 100 outside, no shade on the range so I know what a egg in a skillet feels like)
Some of the loads failed to make PF so I did not test all of them for accuracy and just included the chrono data in case it might be of some use since I had it. I did test the W572 load for accuracy as I am still attempting to figure what if anything W572 does well....

I think a couple of these may have been a bit light powder wise BE86 is normally very consistent vel wise. (re-test at 5.4 and some a bit higher for fun)
