Here are the pics from the other tests. Same standard protocol, 7 yards, group of 5, slow fire, offhand, unsupported.
My Promo loads at 2.8grs
2 - 5 shot groups into 1.8"
No cycling issues. The G42 is working smooth with these loads.
My buddy's Red Dot loads - in this case 2.6grs of Red Dot. 5 shots into 1.6". One out of the five failed to eject.
And lastly, this is the target that I was supposed to shoot at for testing -- but, I left it at home.
OK, maybe next week I'll remember the Glock, the mags, the rounds and the target, all on the same day.
And, my next test will be the Promo 2.8 seated a tad deeper at .955".
Art, I think that the Red Dot will be fine (after break-in) at 2.7 - 2.9 grains.
BTW, I don't know what is up with photobucket, it's rotating the images I uploaded and even when I went through their online editor and re-rotated them, they still ended up wrong. Not in the mood to fuss with it more, so sorry for the sideways images.
