I ran a pretty disappointing ladder this morning.
I was looking for a new load using the 124 grain MPR bullets in combination with CFE Pistol. I tested 5 round groups at 15 yards with 5.0, 5.1, 5.2, 5.3, and 5.4 grains of CFE Pistol. My COL was set for 1.115 with a light crimp. Plunk test was all good. This was my first time trying CFE Pistol and my first time with the MPRs as well. I was planning to run a few thousand later today. Looks like it will be back to the drawing board now though.
My best group with the CFE was at 4\”+. I thought I might be having a bad day so I tossed in a mag of Federal HST and my group dropped down to what would have been a sub 2\” group if I hadn\’t wobbled one out to about 2.5\”. It\’s cold and raining so I will accept that.
Any suggestions are appreciated.
I have no experience with CFE pistol. It looks a little on the slower side than what I like for target use. Did it look like you were getting a complete burn or is your brass a little sooty?
What did the primers look like? Starting to flatten?
You may need to increase the charge a little more to get consistency.
The primers were beginning to flatten at the 5.4 whick is actually above the max charge of 5.3. The powder seemed a bit smokier than others and the brass wasn\’t sootier than the factory federal loads which was fully flattening the primers.
Do you have a faster powder to try?
A rumor that I read is that Federal uses Power Pistol in the 9mm HST loads.
I really like WSF and Vit N320 in 9mm 124 loads.
I\’ll probably run a ladder from 3.8 to 4.2 or 4.3 to see where my sweet spot is. From what I\’m reading it seems to be the 4.1 and 4.2. I\’ve just got to get back home and get in the powder safe to be sure my memory isn\’t lying to me.
