Advice on RMR 115 FMJ, 124 match plated, and 110 .30 carbine?

[1KPerDay]

Just ordered a couple thousand.

1. are the carbine jackets magnetic? Any tips on good load for surplus carbines welcome. I have 2400, 4227, blue dot, li'l gun, and 296.
2. Anyone who has loaded berrys/xtreme plated 124s, is the ogive/seating depth on the RMR 124 similar? I have found I can use berry's and Xtreme interchangeably without changing seating depth or crimp.
3. any advice on the 115 FMJ? I don't expect to run into any issues, but any tips/info would be great. I have primarily loaded 124/135/147s so far.

W296 is an excellent powder for .30 Carbine. You will have to find what your gun likes. Not sure what you are after but I was looking for something that would cycle every time, was kinda accurate and wasn't too hard on the old rifle. Mine will cycle at 13.6 grains but the best load for me is around 14. My buddies will not cycle until he gets quite a bit hotter. I shoot the Extreme or Berry's plated 110 grain round nose. I do use them interchangeably.

 

[1KPerDay]

Thanks. That's about where I ended last time I was working up a load with 296 or a tad hotter. I have other issues with my carbines (extractor/spring/ejector issues) that I need to rectify also.

Get that Warbaby back in action. If there is a more fun rifle on the planet for plunkin' around with I have no found it. I really want a .30 Carbine Blackhawk to go with the rifle but I have not found one for the right price yet.

The .30 carbine are brass jackets that are NOT magnetic.

The 124s have a slightly longer ogive and may require a slightly longer OAL. That said, OAL is something that guys like to play with a lot and I almost never go by what the book says. Typically you are okay to use the same powder data for any bullet of the same weight. Unless your gun can't handle +P loads. And if it can't, you need a new gun.

As far as the 115 goes, just have fun with it. The tooling on our machine is brand new and making perfect bullets. There shouldn't be any problems at all and they can handle pretty much anything you throw at them. We start with a .023" copper jacket and it gets drawn out to about .014" on the walls. That's as thick as many hunting jackets on rifle bullets. They can handle anything you want to throw at them.

Sweet. Thanks man! I noted the different jacket color on the .30 and wondered if they were cupronickel or something.

For a carbine I like 11.5 grns. of 2400 with a 110 FMJ. Whatever you decide to load get the MV around 1750, that's the sweet spot for accuracy. Any ball powder (296) might need a mag primer, or so I've been told. I don't know first hand because I don't use it.

Carbines are a hoot. I've shot mine enough to be able to use the irons with good results at 50 yards. Moving out to 100 soon.

Anyone who has loaded berrys/xtreme plated 124s, is the ogive/seating depth on the RMR 124 similar? I have found I can use berry's and Xtreme interchangeably without changing seating depth or crimp.

I also use same OAL/COL for Berry's/RMR/X-Treme 124 gr plated RN. I usually load them to 1.150"-1.160" with light taper crimp of .378".

With any new 124/125 gr bullet, I usually determine max powder case fill at 1.150" by subtracting average bullet length from OAL/COL and use longer 1.160" if I end up compressing powder charge at 1.150".

advice on the 115 FMJ? I don't expect to run into any issues, but any tips/info would be great. I have primarily loaded 124/135/147s so far

For me, as with any 115 gr FMJ that has shorter bullet base than 124/135/147 gr bullets, I prefer to load 115 gr FMJ shorter at 1.130"-1.135" for greater neck tension with .377"-.378" taper crimp. RMR sizes their 115 gr FMJ slightly larger at .3555" instead of .355" so it should help with improving neck tension and prevent bullet setback.

So far, they have shot very well for me and will be replacing Montana Gold/Winchester FMJ as my new reference 9mm bullet.

Thank you my friend.

Well turns out I had to seat the 124s to 1.125" to get them to plunk in my M&P CORE, which has shown a tendency to require shorter OAL with some other bullets also. The Xtreme and Berry's I load to 1.15". No biggie but I also dropped my powder charge about 10% due to the shorter OAL. At 1.15" they worked in my P226 but since I load for multiple guns I'll have to seat them shorter for the smith. I'll report back with function and accuracy data or at least what passes for accuracy with me (do I hit the plates every time or not).

I've used the 110 .30Carbine bullets.
The particular lot# I received shoot better than Sierra's in my gun.
I use 14.6gr #296, Tula SRP, New ArmsCorUSA brass. About 2,000fps. Holds the "9ring" on SR-2? (CMP carbine match target) at 100yds.

Good to know, thanks.

What is really weird is that I shoot the 147s through my M&P Core and they are seated pretty long. I wonder if they changed something about the chamber. I bought my Core pretty much the day they came out. When did you get yours?

 

[1KPerDay]

They maybe changed the chamber with the "new" barrels. I dunno but mine is pretty short based on my experiences. Got it July 2013. Maybe the 147s have a different ogive or something. As noted the xtreme and Berry's 124s I seat to "normal" 1.15" range and they plunk fine. but MBC smallballs seated to 1.089" (which work well in my Beretta 92FS and SIG P226) jam into the rifling. I haven't tried seating those any deeper for the M&P because I prefer plated/FMJ in that pistol to help keep the optic clear.

 

[J_McLeod]

Only have advice for the 115gr and that's HP38. I use 4.9gr at 1.125".

 

[1KPerDay]

Thanks. What pistol?

 

[J_McLeod]

Springfield XD and XDS. It's my go to 9mm load.

 

[1KPerDay]

Cool thanks.

I'm coming into this thread a little late.

Regarding the 115 FMJ, I did some plunk tests this morning in the two guns I have with the tightest chambers - a Witness Match, and a CZ P-09. The 115 FMJ bullets were touching the lands in the Witness Match at 1.133". The CZ P-09 was at 1.143". Normally I seat my plated Xtreme bullets at 1.145" - 1.150" (they plunk in the Witness Match at 1.168").

So, I just loaded up some test rounds with BE86 from 5.2 - 6.0gn, bullets seated to 1.115". The load data on the Alliant site is for FMJ seated to 1.120", so I'm not too far off there. The case fill with 6.0gn of BE86 and bullets seated at 1.115" appears to be 90%+.

I hope to take them out on Wednesday to test.

 

[1KPerDay]

Thanks. Looking forward to your results.

 

[1KPerDay]

FYI the RMR 115 FMJs plunk at up to 1.158" in M&P CORE and P226. Didn't try longer because I was afraid they wouldn't fit in the Mags. Initial loads with shorter OAL were a little inconsistent but I didn't bench rest them. Hopefully with longer OAL they do better.

 

[Toprudder]

The RMR 115 FMJ plunked at a max of about 1.133" in my Witness Elite, which is the tightest 9mm chamber I have.
