Hello gents,
I've been loading 10mm lately and have some thoughts,
VV N105 is the biggest disappointment, averaging just under 900 FPS on 9.7gn of powder, (9.9 is max)
Longshot is the winner, giving 1250 at 9.3gn, (9.5gn is max)
AA#9 is another strong choice, delivering 1200 FPS at 13gn
Power Pistol is another I'm going to keep pushing. It's also doing 1200 FPS at 9.1gn, (9.3gn is max)
N105 is performing drastically worse than advertised, I'm not sure what the deal is. Im going to increase charge weight to maximum and beyond as well as trying magnum primers. Not even cracking 1,000 at 0.2gn from max is awful performance. Based on their book I should expect 1280.
Im loading all to 1.26" with CCI 300 large pistol primers, and a light crimp on the RMR 180gn FMJ projectiles. I measure on a Labradar chrono. I shoot a Glock 20 Gen4, no mods (I'll circle back with the exact readings but mainly just wanted to compare my thumb in the wind with y'alls on results).
How are your 10mms shooting?
