I’d like to try some of these but haven’t ordered yet. I’ve been loading the Heavy Match Winner and using data for the Hornady 147 grain XTP. Is the same strategy advisable for these as well? My HMW loads are very accurate so that substitution worked well. Does RMR publish their own data? If not, Is there a closer analog than the Hornady where the data matches the RMR better?
Reloading Data for 124 grain RMR Nuke?

I load 124 gr RMR Nuke's with 4.4 grns Bullseye. I use the 124 gr Jacketed Hollow point data from Lyman's 49th and Sierra's 6th Edition.

Actually the Hornady XTP data, while conservative is a fairly close match to the “Nuke” profile and OAL. You could also consult Sierra data, which might be a little more aggressive to use as a starting point. Again, always start low and work up gradually, watching for signs of excess pressure. Your firearm, eyes and fingers will thank you.
edit: the Hodgdon Reloading Data Center does show an RMR 124 gr with loads using Accurate No. 5 and Ramshot True Blue, but I think that may be a previous bullet offered by RMR rather than their own “Nuke” bullet. You could always call or email them to be sure.

What powder?
There used to be published load data from Western and maybe others using 1st generation RMR nuke, but that no longer matches up to the current nuke. RMR does not publish their own. There are three 124 gr JHP bullets that are close matches to the current 124 gr JHP nuke. One is the 125 gr JHP from Sierra, for which there is all manner of load data using a deep seated 1.030 OAL. And lower powder charges to match. Two other bullets that are very close to the current 124 gr JHP nuke are the 124 gr Nosler JHP and 124 gr Speer JHP gold dot. Lots of load data for the Speer, but both of those have OAL of 1.120 or some such thing.........and both of those use lots more powder.
And Option B is to use the 124 gr Hornady XTP load data, and adjust OAL about 0.010 deeper to account for differences in bullet profile. So instead of 1.060 for the XTP, use 1.050 for the nuke. Gets you to same seating depth.
Edited to include the photo below - for comparison:
Left to right.......a lot of similars.......
Sierra 125 gr jhp
RMR - 124 gr Nuke
Precision Delta 124 gr JHP V2 (not an expanding bullet)
Nosler 124 gr JHP ASP
Speer Gold Dot 124 gr JHP

As others have said, RMR doesn’t publish load data, but in the “reviews” section for the bullets individuals sometimes add their load data - not that you should use that, but it does offer a data point.
I start with jacketed 124 or 125 data and try to make sure the bullet seating depth is not less than the published data. Most of the time I load longer than published data.

and they have a link on the website to their Reloading Data Forums- there are topics in there as well outside of the review area.

I was thinking how I can contribute to this thread, then saw your post with the test result "Extremely accurate!". Thanks for sharing your load data! I have an unopened one pounder of Silhouette and was thinking what the best way will be to use it. Your post helped me making up my mind.

Thanks for sharing.
Since I can't find True Blue in my area at a somewhat reasonable price! I have been looking into getting some Silhouette to try.
Very Helpful!!! Thanks Again and God Bless!!!
When considering any powder for 9mm, I always like to see what this guy has to say about it. He is fond of Silhouette too. He is also fond of loading +P and Major........and may be a little crazy to boot, so take his high end loads with a grain of salt.......but he already includes that warning.

They have a great deal of information on that site. They cover a number of different powders. However, they run some pretty hot loads with the disclaimer to not try some of what they have done.
Have to be careful and I'm sure you also believe safety first!!!
God Bless and be safe out there!!!

I'm new to this current Nuke 124 grainer, but it performs well in several of my handguns using HP38/W231. More testing is in order.
That's one of the powders I have. CFE Pistol is another. If I have any left over, I will probably try HS-6 too.

I have loaded several batches with W231, 4.0gr-4.4gr, trying to get a standout load that makes IDPA power factor.
All about the same, accuracy-wise in several different guns.

I've done a few loads using Alliant BE-86 with the gen1 RMR MPR and have more planned.
As others alluded, the external dimensions of the new MPR Nuke is similar to the MPR gen 1, so, I'd expect similar results with the Nukes.
I typically load on the lighter end of the spectrum (with Alliant Sport Pistol). But I've nurtured a love affair with BE-86 across 9x19mm, 40 S&W, and 357 Sig when the goal mid-range to factory-ish levels.
With the 124gr MPR, my objective was ~1150. This was just in casual parity to some factory SD loads spec'd in that range -- for example: Fed 124 gr HST, 1150 MV, 4" barrel.
I believe the new Nukes expand at notably lower velocities thanks to the lead core pre-scoring.
I didn't quite reach 1150 with BE-86 before approaching what appeared to be diminished gains.
But my COAL was a bit longer than most at 1.090" and I'm using a rather light crimp. I may try adjusting both. And also, Ramshot Silhouette is on deck.
To your question, it does seem like Hornady XTP data interpolates fairly closely:
Hornady's 10th Ed: 9x19mm / 124gr XTP / 1.060" / BE-86 / 5.2gr / 1100 fps / 4" barrel (I believe Hornady has a standardized protocol at 74F)
My Loads >>>>> 9x19mm / 124gr MPR / 1.090" / BE-86 / 5.3gr / 1092 fps / 4.9" barrel / 57F
