I have no doubt it would make a big difference. It doesn't take much of a change in the small 9MM case.

Keep in mind RMR sold 2 different JHP bullets.
RMR 124 gr JHP (0.579" length) seated to 1.090" OAL on the left and new "Jack of all trades" 124 gr JHP (0.558" length) seated to 1.040" OAL on the right - Notice the significantly longer bullet base/bearing surface of the new bullet - https://www.thehighroad.org/index.p...g-depth-and-rmr-124-jhp.821665/#post-10555373
The old 0.579" length RMR 124 gr JHP (Left in the picture):
- 1.125"+ fully chambered in older Lone Wolf/KKM barrels.
- 1.090" fully chambered in newer Lone Wolf barrel with almost no leade
The new 0.558" length RMR 124 gr JHP (Right in the picture):
- 1.125" fully chambered in older Lone Wolf barrels
- 1.120" fully chambered in KKM barrel
- 1.040" fully chambered in newer Lone Wolf barrel with almost no leade.

Thanks for the picture BDS.
I have some of both, I was testing the new in house 124 Gr JHP. The old ones are longer with less bearing surface, but with the more pointed ogive can be loaded longer. (.585 long, loaded at 1.120 to 1.125 OAL) They took 5.7 Grs of N-340 with no problem, where the IH 124 loaded much shorter and much deeper was starting to show signs of pressure at 5.5. OAL, and more importantly, how deep the bullet is in the case and bearing surface (Friction), of the bullet.
One way I check loads in 9MM is to see if the cases will all size easily and pass the Wilson gauge. All of these passed last night, so the case heads were not expanded enough to be a concern. I lose 10% to 15% of pick up range brass with this test. No telling what loads some of them were shot with. I scrap the ones that fail.
I have 67 more of those same FC cases still primed with CCI 500 primers. I'll load some IH RMR 124 Gr JHPs up long and see how it affects velocity and what the primers look like. Speer makes a comment in their load manual where seating a bullet .030 deeper in the case raised pressures dramatically. Doubled them actually. It's a tiny case and seating depth matters a lot.
I am not knocking the bullet, as it loaded and shot well. It is just that guns are going to need it loaded shorter/deeper than average and we need to adjust charges accordingly. At my OAL of 1.070 vs 1.120 for the other bullet the IH 124 was .023 deeper in the case, with more bearing surface.

1.075 was the longest the RMR IH 124 Gr JHP would "plunk" in my Shied. I really like 1.070 to 1.075 OAL for this bullet. It looks good there, it feeds butter smooth in everything, and it shoots well there. It will go up to 1.105 to 1.110 OAL and "plunk" (barely) for my Colt Series 80 .38 Super with a 9MM barrel, so I am going to try thee RMR IH 124 Gr JHP there with both 5.7 and 5.9 Grs of BE-86. That is .035 longer than the previously tried OAL of 1.070/1.075. SHould help pressures quite a bit.
I also loaded some up with 5.5 Grs of Silhouette @ 1.070 to 1.075 OAL.
The Western Powder PDF in the 9MM +P section shows from 5.5 Grs with a Sierra 125 Gr JHP @ 1.035 OAL, to 6.4 Grs with a R.E.M. GS @ 1.145 OAL. We can throw out the GS due to the long OAL and the fact it is a bore riding design with much less friction.
They also show 6.0 Grs with the 124 Gr Gold Dot @ 1.105 OAL and the Rainer 124 Gr HP @ 1.110 OAL, as well as 6.1 Grs with the Berrys and Rainer 124 Gr RN, both @ 1.160 OAL.
I'll shoot them after work tomorrow. Results to follow. Should be in the mid to high 80s again, and humid.

I don't have much data in 9mm to compare between the different RMR JHP's, but I have some 357sig data to show the difference. These loads are all tested from a 3.9" barrel using 7.6gr of BE-86. All 3 had very good ES/SD numbers:
This is the original RMR JHP with the longer ogive seated to a COL of 1.150":

This is the current RMR in-house 124gr JHP, also seated to a COL of 1.125". I labeled it JHPih2 to differentiate it from the original in-house JHP:

From tests I have done it seems that the Ginex primers generate less velocity than S&B, but the JHP in-house 2 gave me a higher velocity. The in-house 2 JHP is slightly longer than the original in-house JHP. I would say around .007".

vaalpens, thanks for the posted data. Looks like S&B primers are consistent in reference to CCI primers.
I got S&B primers coming from Cabela's and look forward to doing some comparison tests with them.

We are not talking about the longer tapered one he sold vs the in house one, correct? There were two different in house JHPs? How can I tell which one I have. I would think the latter, since I got them recently. I hope so, or this testing is moot.

The best way to tell, is the price. The new ones start at $99/1000. The old ones are $116/1000. How much did you pay for them?

The one that is $116/1000 was not made by us. We had an agreement with the manufacturer. Now that we have one that we make ourselves, we will be phasing out the old one.

Jake correct me if I am wrong.
The old 124 gr JHP is 0.579" in length and the new JHP is 0.558" in length.

I bought 3,000 of the new In-house 124 gr. JHP from Jake and they measure .558" in length, according to my Starrett micrometer, and .356" in diameter. I got the same measurements with my Kanon Dial Caliper.
Hope this helps.

Ordered 1K to test. I'll try these with Unique and Power Pistol.
It seems BE86 is getting popular. I'll need to add that on my experimental list. For now, Unique and Power Pistol have been very good to me in 9mm.

Okay, thanks for clearing this up for us Vaal
For some reason my reading comprehension has decreased quite a bite in the last few years. Anyway, yes when we first received the machine it was making the more brassy colored bullet profile. I decided that I didn't like it very much so I changed the way we form the ogive. I much prefer the new ogive. It is a little longer bullet but still works well in .357 sig. It also has more consistent and uniform expansion. The body is identical in length but the ogive is just a little more rounded. Walkalong, if you post a picture of the bullets you have, I can give you a better idea of what they are.
The brassy colored ones were maybe only the first 25,000 bullets that we made on the machine so the odds that you got them aren't very high.

Ordered mine the other day, can't wait to test them in 9mm and 357sig! Not sure which powder I will use in 357sig, will definitely try the loads vaalpen posted!

I still have some of the ones on the left. Good bullets that shot well in my plinker load and at max with N340.
The in house ones I have are the ones on the right. I will post today's results later.
That's what I measured as well. +/- .001 on the length.
I shot Load # 114: RMR IH 124 Gr JHP loaded at 1.105 to 1.110 OAL with 5.7 Grs of BE-86 and a CCI 500 primer. It was 90 Degrees and 32% RH, compared to the 87 Degrees and 77% RH the other day.

I shot a poor group with the Colt. Either me or the load, but I didn't gain many FPS for the added recoil and the primers were starting to show signs of pressure. My notes will say to stop at 5.7 Grs.

I shot a great group with this load with one hanging out again, which was surely me. Great load. Soft shooting, very accurate, a great range load.
If you want to push the 124 to the highest velocities AA #5 and HS-6 are better choices, especially HS-6.
The longer ones wouldn't "plunk" in the Shield, so were only shot in the 5" Colt & 16" AR.
Load # 116 got shot in the 3" Shield as well. (1.070 to 1.075 OAL)

The targets.
I shot a good one with 5.7 Grs of BE-86 and the Colt.
I shot a poor one with 5.9 Grs BE-86 and the Colt.
I shot the Shield poorly the first time, so shot another target with it at the end, and did a little better, with four shots close to the crosshairs with two high and one low. Not good, but better. The grip is tough for me.

Looks like your gun likes the 5.5 and the 5.7 loads. The others seem pretty large for 7 yards.
Yes, but the two groups with the Shield is more my having trouble shooting open sights with poor eyes and a narrow grip I am still getting used to. Not bad for a 3" carry gun.
The 5.7 Gr BE-86 and 5.5 Gr Silhouette groups are nice. The Colt has a red dot and I can aim fine and that helps. I was wobblling about an inch with it today. Between the two hashes on the middle of the crosshairs target.
The 5.9 BE-86 group should have been better. May have been me, but I shot those other two good ones.

Same impression here. When new, I noticed the front sight jump quite a bit when the striker released. After dry firing several hundred times and firing several hundred rounds, trigger is smoother and front sight is steady when the striker is released.
My Shield is becoming a favored pistol among coworkers I am currently teaching point shooting/defensive shooting drills with. I am using RMR 115 gr FMJ with 4.1-4.2 gr and 4.4-4.5 gr Promo for training and 1"-2" groups at 7-15 yards off hand is very doable.
I look forward to testing RMR 124 gr JHP loads with my Shield.

I just did some plunk tests last night with my Sig P226, and about the longest I can get that will reliably load with the new 124 gr. HPs in that gun is 1.130". I might dial that down to 1.125" to give myself some more margin. Had some issues with my powder drop last night so I did not get anything loaded, but I hope to load up some loads with BE-86, TiteGroup and HP-38 today. I will post the data when I get it.
Mine would not plunk over 1.075. I look forward to seeing what yours will plunk at.
I need to do some more dry firing with my Shield.
If I concentrate I can hit a 10" steel plate at 18+ yards nearly every time without using glasses. (Fuzzy sights/white dots.) I really just use the dots. I tend to let the front sight get high, or maybe it's what you noted.
I had 163 clean/sized/primed cases after getting all the test load brass ready to load again, so I loaded up 163 rounds of Load #116 using 5.5 Grs Silhouette with the RMR 124 Gr IH JHP @ 1.1070 to 1.075 OAL and a CCI 500 primer. They'll make good practice fodder for the Shield. Not the max you can get with a 124 Gr JHP in 9MM, but close enough for practice.

I went to the range today to test my loads with the RMR 124 gr. JHPs (new style), and got some interesting results.
I tested TiteGroup, HP-38 and BE-86. I started with the SIG P226 Legion SAO (4.4" barrel), but after a couple of sets of TiteGroup, I lost my front sight from the dovetail. I shot a couple of groups without the front sight, but of course I can't tell anything about the accuracy of the rounds, so I switched to my H&K VP9 (4.09" barrel). The problem is that I rarely shoot that gun, and I am not as accurate with it, plus since it is a polymer gun, it is very light and does not handle the recoil as well. I am just not as proficient with it, but I needed something that I could at least *try* to aim!
The weather was beautiful, 69F, 75% RH, and a little windy at 10 mph.
I will post the results for the three powders in 3 consecutive posts.
Setup is as follows:

Some of the SDs are horrible, but that was the type of day I was having all around.
First up, the TiteGroup ladder. I love TiteGroup, and most of my "keeper" loads use TG. The ladder test was a pretty good spread, starting at 3.5 gr. and working up to 4.1 gr. I started meeting Minor Power Factor at about 3.8 or 3.9 gr. These rounds shot nicely, and were honestly pretty accurate until I lost my front sight:

Next up, BE-86.
I tested TiteGroup, HP-38 and BE-86. I started with the SIG P226 Legion SAO (4.4" barrel), but after a couple of sets of TiteGroup, I lost my front sight from the dovetail. I shot a couple of groups without the front sight, but of course I can't tell anything about the accuracy of the rounds, so I switched to my H&K VP9 (4.09" barrel). The problem is that I rarely shoot that gun, and I am not as accurate with it, plus since it is a polymer gun, it is very light and does not handle the recoil as well. I am just not as proficient with it, but I needed something that I could at least *try* to aim!
The weather was beautiful, 69F, 75% RH, and a little windy at 10 mph.
I will post the results for the three powders in 3 consecutive posts.
Setup is as follows:
RMR JHP 124 gr. bullets (new style)
CCI 500 SPP
Federal brass
COAL = 1.125"
Some of the SDs are horrible, but that was the type of day I was having all around.
First up, the TiteGroup ladder. I love TiteGroup, and most of my "keeper" loads use TG. The ladder test was a pretty good spread, starting at 3.5 gr. and working up to 4.1 gr. I started meeting Minor Power Factor at about 3.8 or 3.9 gr. These rounds shot nicely, and were honestly pretty accurate until I lost my front sight:
