Several years back, I scored some Hi Skor, and decided to try to make it work in 9mm.

Well, time sure flies by. Today I finally got around to wrapping this up.
I've been treating Hi-Skor like Red Dot, as most data I found seems to show comparable loads.
My conclusion, Hi Skor is not 9mm friendly. It seems too bulky to work well. The best groups were in the 3.6-3.8gr range, with failures to feed.
4.1 gr - large pattern. feeds nicely, cases fly all of 6".
4.2 gr - pattern tightens slightly, a little more pop
4.4 gr - pattern opens up, more pop, most cases manage to make it to the ground, not sure any actually cleared the bench on the way there
Everything over 4gr shot nice, and would be fine for plinkers in a pinch. No signs of any pressure. And maybe a different gun would be happy with one of the loads.
Anyway, stopped at 4.4gr simply because that appeared to be a slightly compressed load. It is very close with 115 gr bullets. At that, I don't think these are going very fast. Feels almost like a 22 compared to a standard round. I know, that and a dollar might buy a cup of coffee. I didn't bother with the chronograph since it wasn't worth the effort for these few rounds.
I suspect 124gr bullets would be better, but I have a very good load for that now, and with bullets in short supply....
