I’ve been on a kick lately of experimenting with different VV powders in handgun cartridges. It’s been fun. 1# of N105 arrived yesterday. I loaded 3 ladders - 2 in 45 Colt, 1 in .357 magnum. I hope to go shoot them and report results on here today. I’ll shoot them from 20” Henrys @ 50 yards for accuracy and velocity. I’ll load more of the winners and chrono from revolver later. Usually the most accurate loads in my rifles are also pretty good to outstanding from my revolvers.
Here are the particulars:
45 Colt
225 FTX
Winchester brass trimmed to 1.210
WLP primers
5 rounds each N105 @ 15.7, 16.0, 16.3, 16.6, 16.9, 17.2
COAL 1.60
45 Colt
250 XTP
Winchester brass trimmed to 1.265
WLP primers
5 rounds each N105 @ same charges as above
COAL 1.575
.357 Magnum
Zero 158 jhc
Starline brass trimmed to 1.28
Federal sp magnum primers
5 rounds each N105 in .2 increments from 10.1 - 11.9
COAL 1.585
* side note - to empty .357 brass I shot a box of 50 125 xtp over 8.4 grains W-231 I had stashed. I used my 4.2” GP100 (fiber optic sights) with my arms resting on my range bag for stability. 25 of them went into a 2” circle @ 15 yards. The other 25 stayed in a 6” circle @ 25 yards and most joined the 15 yard group. Not too shabby for me. I highly recommend this combo for mild SD or light hunting from a carbine. Felt recoil is just a bit above what you would expect from .38 special +P. 1306 fps from 4.2”, 1581 fps from 20”.
