Reloader98

So I made a video of the gun while disassembled, I attempted to do the plunk test with one hand while making the video, forgive my poor video work. as I’m pretty new to 9major and not doing the plunk test a whole lot before this, it would be much appreciated for y’all to watch it and tell me what you think. video: https://photos.app.goo.gl/3QrfijaGKBizvEat8

Thanks Steve RA, I’ll have to try that out, when I loaded them, the seating of the primer felt pretty tight, as new brass should, but I’ll try out different brass.

I thought the primers were flattened, because they looked very different when they came out, mild cratering on a couple of them as well. And can you eleborate more on the brass issue? If it fits the chamber and moves freely, what does that mean? Isn’t it supposed to be right at the barrel hood ? Or am I thinking of the plunk test incorrectly? thank you for your replies gentlemen.

Correct me if I’m wrong but if the primers are blowing out at 6.8 ore 6.9 wouldn’t they blow out at a height drop weight?

I wanted to try some other ones but autocomp and titegroup were the only ones I could find in stock for a decent price and I can’t use titegroup cuz it’s WAY to fast. Do you think a change in COAL could help? Or is mostly the powder?

Hello everyone, I got my first open gun a couple days ago, a JL Hardy shorty 4.25” KKM barrel with comp and two popple holes. It came with 1 MBX 170mm magazine (used in load testing) and two 140 STI mags and 1 170 STI mag. I’m having two issues. 1. primers popping out of cases and jamming the gun 2. Rounds diving up into the barrel and jamming (could be the MBX mag, unsure) loads tested: - unfired, new, starling cases for both powder weights. -montana gold 124gr JHP -Autocomp powder -CCI small pistol primer -COAL: 1.160 first load: 6.8 gr autocomp FPS: ranges between 1375-1400 (averaged about 1386) second load: 6.9 gr autocomp FPS: ranged between 1390-1419 (averaged around 1397) The gun worked somewhat well, groups were great, but the issue was the primers popping out, like listed in the pic below. question: what can I do to remedy this, am I using to much powder? the rounds jamming into the upper left of the barrel could be the MBX mag, but I’m more worried about the primers blowing out. what’s y’all’s take on what I should do? link to photos of spent brass. https://photos.app.goo.gl/239MZAJfC1vFcKyA7

Thanks Brian !

Thanks for the reply Brian ATL, I’ve been hoping some other people had Hardy shorties. Have you tried autocomp in yours ?

I’ve looked at that some topic all day today, I e decided on autocomp since it’s all I could really find. The guy I bought the gun from said his load with a 124 gr JHP was 6.8-6.9 gr of autocomp. Only thing to figure out now is seating depth. What’s your take on seating depth with MG 124gr JHP in a KKM 4.25” barrel?

Have any suggestions on good burn rate chart?

Gee thanks Sarge, I’ll take that into consideration, does it make a difference that my barrel is 4.25” I have a JL hardy shorty with a KKM barrel.

You know I ordered some Winchester Autocomp, but I keep getting mixed messages from people, some say it’s snappier, and more dot movement, some say it’s pretty flat, I have popple holes in my gun that I’ll have soon, so I hope it’s flat, but I keep getting mixed signals

That’s what I’ve heard, seems like VV powders like 3n38 and others tend to fill the case more and thusly work the comp more. Downside is VV powder $$$. With a Dillon 650, that stuff will go everywhere, that’s why I bought some autocomp, hopefully it’s not to snappy with the two popple holes and a comp. looking at a burn rate chart for Hodgdon, seems like win 231 is a good option as well, but just like AA#7, it’s about as common as woman over 30 without kids or a divorce.

I appreciate the experience and suggestion, but the shortage right now is the only reason why I’m going with autocomp, otherwise I’d be buying VV powders but now their to expensive. Not to mention the egregious prices I’ve been spending on primers, ($75) at my local Cabelas, on the Tara occasions we get them and hide em before customers take em, I.e. I work their. Lol

Have you tried CLR? The famous cleaning product for like grime and stuff in showers? I saw a YouTube video about an ELR comp shooter that uses it to clean his muzzle brake and sometimes barrel( barrel cleaned heavily afterward to prevent rust). apparently it does a great job on compensators if you soak them overnight

Thanks superdude, oddly enough, I just read that same article like 10 minutes ago, what a coinkydink

Thank you gentleman, as this is my first open gun, I kinda figured titegroup was a little fast, I have discovered that WAC is IN STOCK at powder valley for about $26 per 1# of powder. Think I’ll have to buy a couple pounds, I’ll link it in this reply in case any of you are looking for that powder. I also read some articles and reloading 9 major, seems like autocomp is the way to go without getting a powder from VV that cost me an arm and a leg. thanks to everyone that replied. link to powder valley: https://www.powdervalleyinc.com/product/winchester-autocomp/?__cf_chl_jschl_tk__=pmd_6b031324af95812d6c4bf85de5aa56db787e523f-1627340463-0-gqNtZGzNAfijcnBszQd6

Well from what you guys have told me, it’s group is an absolute no go for sure, what powders would be good? That y’all have seen available recently?

Hello all, wanted to get some opinions on using titegroup powder for reloading 9mm major. Unfortunately due to the ammo/powder shortage. I really can’t buy many other powders, not for a feasible price anyways. bullets: MG 124gr JHP case: mixed brass, mostly starline primer: CCI small pistol powder: titegroup gun: JL. Hardy shorty 4.24” KKM barrel large two port comp and two ports in the barrel itself (phot attached) just wondering if anyone has any experience loading with a gun like this as it’s my first open gun. I’ve heard titegroup is not the best powder for 9 major as it’s pretty fast, have any suggestions for making major PF with this powder? is it possible while being somewhat safe? thanks a bunch

I saw an ad once about those coming out this year but I don’t think it will, doesn’t seem practical for them to do

That’s the Megan fox of guns lol

What open gun do you have? Is it custom ? Or something semi production like an STI DVC O

I definitely am lol
