Well, I picked up some BlueDot to try out for some reduced loads.
I loaded a few with 7gr under the 52gr SP's. Even though I wasn't able to group them..I just wanted to test a couple out, so I was impatient and shot them off handed.. I have to say I had a ball, just shooting off what little I did. The 7gr load was loud, but not ear ringing loud. Slightly louder than a 17HMR. I wish I could have Crony'd them, but all in time.
I am guessing, and only a guess, that these were moving at slightly under Hornet speeds.
I can't wait to load up some more in varing weights to see how they do.
I post back when I have something to report
