I went to the range today to test my loads with the RMR 124 gr. JHPs (new style), and got some interesting results.
I tested TiteGroup, HP-38 and BE-86. I started with the SIG P226 Legion SAO (4.4" barrel), but after a couple of sets of TiteGroup, I lost my front sight from the dovetail. I shot a couple of groups without the front sight, but of course I can't tell anything about the accuracy of the rounds, so I switched to my H&K VP9 (4.09" barrel). The problem is that I rarely shoot that gun, and I am not as accurate with it, plus since it is a polymer gun, it is very light and does not handle the recoil as well. I am just not as proficient with it, but I needed something that I could at least *try* to aim!
The weather was beautiful, 69F, 75% RH, and a little windy at 10 mph.
I will post the results for the three powders in 3 consecutive posts.
Setup is as follows:
RMR JHP 124 gr. bullets (new style)
CCI 500 SPP
Federal brass
COAL = 1.125"
Some of the SDs are horrible, but that was the type of day I was having all around.
First up, the TiteGroup ladder. I love TiteGroup, and most of my "keeper" loads use TG. The ladder test was a pretty good spread, starting at 3.5 gr. and working up to 4.1 gr. I started meeting Minor Power Factor at about 3.8 or 3.9 gr. These rounds shot nicely, and were honestly pretty accurate until I lost my front sight:
