RMR's new 9mm/380 95 gr FMJ - Right bullet for carbine loads?

[LiveLife]

Just got an email from RMR announcing their new in-house manufactured bullet - 95 gr FMJ that can be used for 380Auto and 9mm, particularly for carbine loads - https://www.rmrbullets.com/products/496213195874304-380-95-gr-rmr-fmj-round-nose-bullets-new



"Announcing a new member of the RMR family!!! The 9mm/.380 95 grain FMJ was born last week! I learned my lesson about announcing new products before we had enough made to make sure the machine could continuously produce them. This time we have plenty made and we know the machines can make them all day long to keep up with orders. I apologize for the delay in bringing these to the website. We were expecting to launch these right after SHOT show but as usual, nothing ever goes as planned. But now we feel we've perfected them and they can go home to you!!! As usual, all prices include shipping. Larger and smaller quantites are available."

1,000 - $75 ($71.25/1000 after 5% THR discount)
2,000 - $146 ($69.35/1000 after 5% THR discount)
4,000 - $284 ($67.45/1000 after 5% THR discount)
12,000 - $828 ($65.55/1000 after 5% THR discount)

When I started testing 9mm carbine loads at 50/100 yards, 115 gr was lightest I was planning to test. Then Walkalong suggested I test lighter bullets as they produce flatter trajectory and less vertical stringing at longer distances - https://www.thehighroad.org/index.p...n-9mm-40s-w-45acp.799231/page-3#post-10245856

With RMR 100 gr thick plated Hardcore Match RN rated to 1500 fps, I got sub 2" groups at 50 yards but the 100 gr HM RN is no longer available. With the new 95 gr FMJ, looking forward to smaller groups from my carbines.

Just ordered 4000 using thehighroad5 code for $269.80 (Must enter THR ID in the remark box to receive the discount).

Eagerly awaiting test results.
With 4000 hopefully you have enough to find something that works well
The 124 RN, 124 FN and 147 FN FMJs that I have used are quality bullets, I would imagine the 95s will be also.

bds,
Will be interesting to find out what The 9mm/.380 95 grain FMJ diameter is.

I will put some of these up for PIF - https://www.thehighroad.org/index.p...r-pay-it-forward.760272/page-86#post-10850795

I've had great results with the RMR 115fmj in my carbine. I get very consistent 1.1" groups @ 50 yards, and less than 2.5" @ 100 yards. I have not even bothered to try anything else, it worked so well. Now I am tempted to try something else (sigh).

FWIW, I get ~1500fps MV, using 6.1gn Power Pistol. I've gone up as high as 6.6gn, but the groups opened up. Just for fun, I have even shot them out to 300yds, hitting steel silhouette targets fairly consistently. 200yds is easy. Lots of drop and spin-drift, though.

I have a friend with a Labradar chrono, so we used it to measure the velocity out to 100 yards. It was very interesting to see the velocity of the bullet as it traveled downrange.
(velocities are average of 10 shot group)

5yds = 1499
20yds = 1429
50yds = 1230
75yds = 1206
100yds - 1127

It would be interesting to see how the new 95gn bullet performs downrange.

These new bullets are interesting, but for those that shoot competition, remember you have to make power factor which means you'll need a good bit of speed to do it. And you have to knock down steel with them too.

And I believe the power factor formula favors weight over velocity.

It depends on the sport for sure. SCSA (Steel Challenge) matches do not have a power factor requirement, so as long as they are accurate, can knock down the targets on the plate rack and cycle the gun 100%, you can load them to whatever PF you like.

USPSA requires power factor minimums for sure.

For SCSA, I am currently shooting 100 gr. Xtreme .380 bullets over a light load of HP-38/W231, and they work GREAT. I am anxious to try these new RMR bullets.

FWIW, I am referring to pistol shooting, not PCC. Sorry if that was confusing.

 

[someguy2800]

Our local informal action pistol league has no power factor, however they have plastic self healing knockdowns that you have to be able to knock over. interestingly I've found that the lower the velocity, the more effective it is as knocking them over. ssssh, don't tell anyone

 

[Ruger 15151]

Do you see more advantage loading 380 bullets in 9mm cases in PCC? Is there any advantages in pistol?

 

[LiveLife]

As the thread title indicates, I do believe that lighter 95 gr bullet will provide advantage in carbines over 115/124 gr bullet, especially at longer distances (50/100 yard comparison test groups should prove/disprove this).

Bullet drop expressed as vertical stringing gets worse as distance increases from 50 and 100 yards.

Even with lighter 100 gr RMR HM RN plated bullets that produced sub 2" group at 50 yards, 100 yard group shows definite "elongation" of group from bullet drop vertical stringing - https://www.thehighroad.org/index.p...n-9mm-40s-w-45acp.799231/page-3#post-10286159

With 115/124 gr FMJ bullets pushed to near load data max charges, vertical stringing was much more pronounced (tested 100/115/124 gr chrono numbers) - https://www.thehighroad.org/index.p...n-9mm-40s-w-45acp.799231/page-4#post-10338994

Testing with 100 gr RMR HM RN plated bullet was kept just below the advertised max of 1500 fps. With RMR 95 gr FMJ, I am planning to push the velocity upwards of 1600+ fps which should reduce vertical stringing.

IMHO, in rifle, vertical stringing has less to do with max velocity or bullet weight, and more to do with barrel harmonics and extreme spread in velocity. I pushed my 115 loads to near 1600fps but the groups opened up, 1500fps gave the smallest group size.

As the thread title indicates, I do believe (and endorsed by Walkalong)

This is the second time you have said that, yet I never alluded to this AFAIK. I like to shoot the 90/95 Gr at high speed in pistols for the fun factor (Gets there fast, drop is minimal), but it doesn't do anything for me in a carbine.

I stand corrected and revised my previous post.

Here are your actual posts I have been misquoting as endorsement for using lighter bullets for 9mm carbine loads - https://www.thehighroad.org/index.p...n-9mm-40s-w-45acp.799231/page-2#post-10222082

My RRA is 1 in 10 ... I really do need to do some formal 100 yard testing with a scope, but I do know my 124 Gr load will pop clay pigeons all day long at that distance with the red dot that completely covers them. I haven't shot the 88 or 90 Gr loads at distance yet. Just barely starting with them. They are fun to shoot from a pistol.

https://www.thehighroad.org/index.p...n-9mm-40s-w-45acp.799231/page-2#post-10223525

I have pushed the Remington 88 Gr JHP to nearly 1700 FPS from the RRA AR. I haven't chronoed the 90 in the AR yet. I am getting nearly 1500 FPS from a 5" 1911. They get to the target in a hurry.

So I guess the comparison between 95, 115 and 124 gr FMJ will be my "formal" testing of bullet drop/vertical stringing at 50 and 100 yards.

FWIW, I will be using both 1:16 Just Right carbine and 1:10 PSA carbines.

Will definitely keep that in mind for powder work up.

 

[Ruger 15151]

I should have asked my question more clearly.

I was trying to understand if there has been any testing to see if a lighter bullet is advantageous to accuracy over a 115/124 gr bullet in pistols.

 

[kidneyboy]

Looking forward to your testing bds. I don't generally shoot out past 50yds and have had excellent results with RMR 124 JHP MPR at that distance. But my curiosity is piqued with these lighter boolits.

 

[lauderdale]

BDS know were i can get a decent price on a J.R. 9mm conversion barell besides there cite? threaded non threaded. 300+ is steep! Shoot me a PM if possible. Thinking it would be a kit as the internels /buffer tube etc. might be differnt. Thank you. John
