Good point Rich
I am also using HBN in the bullets.
Should have stated that.

All speeds from a magneto chrono.
Holy God Rich,
What brand barrel are you using?
Sounds like you may be switching to h1000 instead of rl26.
I went back out to proof the 61.5 gr. load and did even better so I guess I may have a keeper! I also shot this 2 shot load with 62.4 grs. (all I had) This H1000 is looking mighty good.......Rich

Hey Rich with that 2.988 coal, how much are you jumping those? I figure our chambers should be similar in dimension being cut with your reamer & all. Ijust picked up a few 100 of the 143's for testing. Thanks, Kevin
Hi Kevin....Looks like you are having fun with the SS! Pretty impressive velocities with the RL26. I would add though that 65 grs. of RL33 is a pretty mild load with a 140. I can shoot 66 behind a 160 Matrix for 3130' in a 26" barrel. Keep the data coming.....Rich
p.s. Not knocking your Crony, but you may have more velocity than it is reading. My magneto speed gives me 3305' with 60 grs. RL26 behind a 143 with only a 26" barrel. I would think you would gain more than 35' with a 30"?
