I managed to find time today to pull down 100 rds of hot loaded 9mm I picked up a while back. Glad I bought them just to get them out of circulation. These were badly corroded on the inside, some badly caked powder, and weird mix of flake, short cylinder, and something that looks like 4F pyrodex.
Edited to add: it was all labeled as N340 (50 ea) and N350 (50), these are both short cut extruded powders. But the powders that came out of the cases were a mix of 2 or 3 different types of flake and extruded.
Also the pulldowns included 50 pieces of 9mm headstamped "MM" "6" "43". That is one I can't find in the intl cartridge collectors assoc lists. These were likely factory rounds, not the n350 they were labeled.
Somewhat controversial cartridges you have there.I was digging through some spent 9 mm casings and ran across a couple of strange headstamps. Maybe you guys can help me out. They both look vintage. The first has 9 at 10 o’clock and MM at 2 o’clock with 43 at the bottom and an annular primer crimp ring. The second has DI at the 10 position...forum.cartridgecollectors.org
Good to hear that you’re getting back at it. Hopefully being in the reloading room will take your mind off of everything that you have been dealing with lately. Stay strong AJWell it's been awhile since I'd been out there. Got a text and into a conversation with @Yamifrk last week and it really picked me up and got me motivated to get back out and on it again. The Pro 2k was still set up for 38s from months ago, so I ran 100 after work today. Spent yesterday cleaning up my horribly overgrown range, then unpacked some stuff and put it back on the shelves, as it looks like I'm gonna stay for a few more yrs.
I go on afternoons tomorrow until they figure out this strike, so I reckon I'll go out back and make some brass to tumble in the morning.
It's good to back in the saddle, and thanks Kenny
Congrats The 25 acp is the smallest bullet ive ever built. What gr bullet did you use? I loaded some 25 acp PPU 50 gr rn bullets with 1.4 gr of Win 572 in new PPU brass@ .9040. The data that Lee sent with their dies is what I used.View attachment 1172286View attachment 1172287View attachment 1172285
Finally found a place with .25acp brass in stock so I got a hundred fired brass.
Of course out of the hundred four were berdan primed so I loaded up 96.
The little rounds were tricky but doable.
Of course my “universal” hand prime wouldn’t hold the little shells so I had to prime them on the press. It surprised me how well that worked. I kinda like it.
Thank goodness there was a powder through expander die in the set I got. No way would my powder drop reliably meter 1.4 grains of powder. I trickled every round and did a visual verify to make sure they were all at the same level of fill.
The spec said .91” for COAL but the bullets had a cannelure so I crimped to the cannelure at .895”. Is that the right thing to do? They all plunked perfectly in the barrel.
I used CFE-P just because I found load data for it and I had some.
I used the PPU 50’s also, but loading to the cannelure gave me a slightly shorter COAL.
Found an error...
RMR 135gr FMJ-TC. Most of them.
Found one that weighs 123.5gr.
That seems like a big difference. I have loaded RMR's 124s with the same powder charge so I don't think it would have been dangerous but I wonder if I would have noticed it.
