I was able to get out and do a little chrono work yesterday...between the rains <sigh>
I got the idea of using this general data from posts by @Outpost75 and @Lost River Not their data but my extrapolation from various posts.
I wanted some practice ammo that would service potentially as a SD round and would play nicely with my HKS speedloaders for my LCR 327. I have several boxes of 85 gr XTPs in my component stock. So why not?
IIRC the suggested threshold for expansion was mentioned to be 850 fps.
All loads shoot better than I do...
