RMR's own line of Thick Plated bullets

I kinda like "RMR OMG" as that was my and other people's response.
I like that.

Your tag line would be, "That will be your reaction, when you see the improvement that comes with using our Target/Competition Grade Bullets"

Depending on the demographic you're after, this might work to your advantage. I think it would appeal to younger shooters who have a lot of disposable income and aren't yet locked into older suppliers

How about RMR HT "Holy Toledo!"?

Or RMR OHT, "OMG! Holy Toledo!"?

That way, we transcend all demographics. ;)

Jake, just stop us when you think we have gone too far (or have we already? :D)
 
I think they should name it RMR BDS. This will recognize "bds" for all the effort he has put into testing the bullets, and it will also mean RMR's BaDasS (tough, uncompromising, or intimidating) bullets.

I had to spend most of today doing repairs on our suburban so I did not get to do comparison range test with W231/HP-38, Titegroup and AutoComp but wanted to test WST for 9mmepiphany and continue on with BE-86 testing.


9mm 124 gr RN with Winchester WST / Alliant BE-86:

Determining maximum case fill for RMR 124 gr TP RN:

Because WST can be spikey at higher charges (so I've been told and perhaps why Hodgdon don't publish load data for small case volume 9mm ;)), I wanted to first calculate the maximum powder fill in the case before I start compressing the powder charges.

I measured several unsized cases and they ranged from .740"-.745". After resizing, they grew to .745"-.750". Since 124 gr RN bullets averaged .680" in length, longer 1.160" OAL/COL was used for greater margin of error and I did a little math:

1) 1.160" (OAL/COL) - .680" (Bullet length) = .480" (Maximum powder case fill)

2) .745" (Shorter resized case length) - .480" (Max case fill) = .265" (Distance from case mouth to top of powder charge in case)

I measured down from case mouth .265" with the end of calipers and 4.0 gr of WST was the maximum powder charge I could fill the case before I start compressing using 1.160" OAL/COL (I did the same with BE-86 and 5.2 gr was max case fill). I was hoping to test 4.3 gr of WST but perhaps on future range test, I may test 4.1/4.2 gr at 1.160" or use longer OAL like 1.165"-1.169".

For BE-86, I referenced Alliant published load data for 125 gr lead RN with 5.7 gr max charge and 124 gr FMJ with 5.8 gr max charge at 1.120" OAL/COL. Since 5.2 gr was max case fill, I figured it was a low enough powder charge to range test, especially at longer 1.160" OAL.

All the test rounds were taper crimped to .377".


Range test:

Glock 22 was used with KKM 40-9 conversion barrel at 25 yards with hands resting on top of a small ice chest. I did load limited number of 4.0 gr WST/5.2 gr BE-86 rounds at shorter 1.140"-1.150" OAL to satisfy my curiosity which I tested at 15 yards.

4.0 gr WST load recoil felt mild (less than my W231/HP-38/Promo reference loads: 115 gr FMJ with 4.8 gr W231/HP-38 at 1.135" OAL, 124 gr FMJ/plated RN with 4.3 gr W231/HP-38 at 1.135" OAL and 124/125 gr lead RN with 4.0 gr Red Dot/Promo at 1.125" OAL) and I did not notice any muzzle flash but the 5.2 gr BE-86 load recoil felt moderate (more than W231/HP-38/Promo loads) and I noticed around 6" muzzle flash.

WST load produced smallest 5-shot group of 1.5" and while BE-86 load produced smallest sub 2" shot group, sub 1" 4-round cluster definitely shows promise as an accurate load.

Ryan, I plan to do more 9mm testing with other powders (W231/HP-38/Titegroup/AutoComp) and also do comparison range tests using Winchester SP vs Fiocchi SP primers. I plan to test 4.1/4.2 gr of WST on future range tests probably with longer 1.165"-1.169" OAL/COL.

To help you with your reloading log (if you don't have one, it's a good idea to start one, especially if you want to use it for future reference), here are my loads I have tested so far:

RMR 45ACP 230 gr TP RN:

- Untrimmed mixed range brass
- Winchester LP primer
- 5.0 gr of HP-3
- 1.200" OAL/COL
- .471" taper crimp
- Lee carbide dies
- 5" railed Sig 1911 XO TacPac with factory barrel (no trigger job)

Note - If your barrel has longer leade/slower start of rifling, you may need to use longer 1.230"+ OAL/COL.


RMR 40S&W 180 gr TP RNFP:

- Untrimmed mixed range brass
- Fiocchi SP primer
- 6.1 gr of BE-86
- 1.155" OAL/COL
- .421" taper crimp
- Lee carbide dies
- Gen3 Glock 22 with factory barrel (no trigger job)

Note - If your barrel has shorter leade/quicker start of rifling, you may need to use shorter than 1.145" OAL/COL.


RMR 9mm 124 gr TP RN:

- Untrimmed mixed range brass
- Fiocchi SP primer
- 4.0 gr of WST
- 5.2 gr of BE-86
- 1.160" OAL/COL
- .377" taper crimp
- Lee carbide dies
- Gen3 Glock 22 with KKM 40-9 conversion barrel

Note - For 1.160" OAL/COL, 4.0 gr WST and 5.2 gr BE-86 were the maximum charges before powder compression using .745"-.750" resized case lengths (FYI, Glock/KKM/Lone Wolf barrels will accommodate typical FMJ/RN out to 1.169").

Thank you bds.

Interesting how you arrived at your OAL...much better than the method I'm using (hey, asking around as worked for ages)

I started with 4.0 grs loaded to 1.150" and slowly worked up to try to get to 1050 fps. 4.4 grs got me there, in a 4.4" bbl M&P9, and 4.5 grs. gave me some cushion. At 4.0 grs, my cases were just dribbling out of the ejection port

Looking for consistency, 1.150" was pretty erratic, I seated down to 1.140" and then 1.135" (on my progressive press, it is actually around 1.143" and 1.137")

To test the 124 gr RMR and the 124gr Xtreme, I've backed off to 4.2 gr. But I am loading to OAL of 1.145". (untrimmed mixed brass, CCI 500 primers)

Looking at your data, I should likely back off on the OAL a bit
 
bds, thanks again for the detailed write up. It is always very interesting for me the thought process you go through to to get to a specific load. I learn a lot from how you approach these load workups.

1) 1.160" (OAL/COL) - .068" (Bullet length) = .480" (Maximum powder case fill)
Please note that the listed bullet length should probably be .680" instead of the listed .068".

It sure does. Best advice I got when I started match shooting was, "If you want to improve your stage scores, talk to the shooters winning the matches. And if you can, talk to the top regional match shooters, not the local match shooters"

I started with 4.0 grs loaded to 1.150" and slowly worked up to try to get to 1050 fps. 4.4 grs got me there, in a 4.4" bbl M&P9, and 4.5 gave me some cushion. At 4.0 grs, my cases were just dribbling out of the ejection port
I was aiming for 4.3 gr of WST to get above 1050 fps for 130 PF but this was my initial range test and I couldn't set up a chrono. I will be moving next month and will be able to post chrono data with my range tests. In the meantime, I plan to range test 4.1/4.2 gr.

Ooops, good eye! I must have been tired from working on the suburban all day in the heat. :rolleyes:

<corrected previous post>
 
Like them, getting ready to order some.

I had really good luck with the ones BDS gave me PIF.
I am no where near as good a shot as he is but this is 25 rnds @ 10 yards
230 RMR plated 4.7gr HP38 Win LP primer


[B29 so the X ring is about 7/8 W * 1 1/4 H, left 9 edge to right X edge about 2 1/4]

Thanks guys, I was shooting a little left to start but adjusted and got them in the middle. Really happy with that load.
I am pretty sure the load and the pistol can do better than that the limiting factor is me.
(Can't wait for my eye Dr Appt. next month, need to get some presctiption shooting glasses)
OAL was 1.23 per BDS.
I am going to have to send all my unloaded bullets to him so he can work his magic on them before I load them.
Either that or maybe some of his skill rubbed off on me when we shook hands! :D

Just ordered some!

1000 RMR thick plate .45
500 RMR thick plate 9mm.

Now if I can just get BDS to install his patented micro rader guideance system before I load them........
 
Quick question for you guys. Would anyone like to see a 180 grain 40 with a similar profile to the 45 230? It would have the really long body and a very blunt round nose. Essentially it will have a TON more bearing surface than the current offering.

Actually, I gotta give credit where it's due. ;)

What really happened is Jake runs his new bullets through special "boot camp" where they learn the art of "rotational stability" as Jake stretches the bullet base. And with special lead alloy diet, they firm up to resist being squished when taper crimps are applied to maintain greater neck tension for more consistent chamber pressures. So by the time they attend flight school, they are ready to really fly!

So it's not me but Jake who "trains and conditions" the new bullets to shoot more accurate. :D
 
Okay, sometime next month we will be getting 147 grain 9mm and 124 grain flat point 9mm. Also, we are expecting the 115's to be up an running again middle of next week!
