Well, I'm back from the range. I only fired 4 rounds, as it was 30 degrees, spitting snow, and wind blowing 30 mph. Didn't even try to hang paper targets, and using the chrony would have been a problem, as the skyscreens would have tried to take flight.
I did pop a gallon water jug to assess the potential to disrupt molecules of water in a hurry. The jug split nicely. I did pop a 1 inch rough pine board with a 16 lb bowling ball behind it, tearing an egg yolk sized chunk out of the bowling ball. I suspect this load, 5.5 grains of Red Dot, is running somewhere near 1100 fps.
The SA Champion, a 4 inch 1911, fed and functioned perfectly, with no FTRB or any other issues. It shot pretty well where I pointed it too. Though conditions were lousy, and I shot tradtional from not over 10 yards, the elevation was pretty durn close to POA.
I know this is off topic here, but to me it represents an interesting sidebar to the EPP UG 45 150 story.
If the chrony proves the load to run 1100 fps, it ends up about 20% more energy than a 230 ball load, with 10% less momentum (recoil) and a hair less TKO (10 vs 11).
Might be a good bowling pin load owing to the energy levels with modest recoil?
So, DD ole pard, ya might wanna consider chatting with the folks at Brianenos.com or any of the other 1911 oriented sites. They might be interested in the EPP?
