I finally got a chronograph going and wanted to test the 69g SMKs I have been using. For my meager skill I was decently impressed.

I am using Markm's suggested load of 22.9g of H322 and a Wolf magnum SRM primer.
mixed LC brass
2.25 OAL
Blackhole Weaponry 18inch barrel

I fired 10 shots through the crono and got
an average velocity of 2703
Standard deviation of 34
extreme spread of 98

I then fired the remaining 5 I had loaded for testing up at 100yards using a SWFA 12x scope.

I fired the first 4 then adjusted the scope for the 5th. 100yd groups are great now I just need to figure out how to get the SDs and ESs down to start pushing the load out to longer ranges. I'll take any suggestions to drop that SD down. For comparison, I fired 10 rounds of ADI 168g SMKs though my bolt action and got a SD of 8 so I know single digit deviations are possible.
