Dirtfarmer, et al,
I finally got the chance to run my loads over the chrony and check for repeatability. Both were a pleasant surprise.
Avg speed for 7 rounds over the magnetospeed = 2794fps (24" barrel) ES 11 Sd 9. 5 shot group right at .411
Next, I took it on the stand and popped a little axis doe at 109 yards. On the shot, her back end dropped and she did a 180 on her side and never even kicked.
Exit wound was around 1.75" with very little blood-shot meat in the shoulder. ( figure she live-weighed about 120)
Looking forward to hearing how it works for you DF
