Wish I could tell you yes, but it wouldn’t be true.
So far I have only chronographed.

I have seated the 124HP RMR Bullet at 1.060 and never had a malfuntion. So far at that seating depth, the bullets functioned flawlessly through Canik Mete, Canik TP9SF, Springfield Hellcat, Sig P365, Sig M17, S&W SD9VE, and Taurus GX4.

124HP RMR, COL 1.060, Springfield Hellcat 3.1″ Barrel. 6.0 grains Ramshot Silouette 1151fps ES27 SD11. 5.9 grains Ramshot Silouette 1139fps ES19 SD7.

124HP RMR, COL 1.060, Upgraded Smith Wesson SD9VE 4.0″ Barrel. 5.9 grains Ramshot Silhouette 1187fps ES22 SD8

124HP RMR, COL 1.060, Canik 4.5″ barrel,
5.9 grains Ramshot Silhouette 1215fps
5.7 grains Ramshot Silhouette 1168fps
5.6 grains Ramshot Silhouette 1161fps

Silhouette is not my go to powder. It was all I could get when the Plandemic came around, I prefer HP38/WIN231 the most, CFE Pistol was super awesome with 124HP RMR, Ramshot Zip worked great with RMR 124HP, Accurate #7 worked flawlessly with the 124HP RMR’s too, but you have to use quite a bit of it according to published books, and in my own experience.

I am glad you got everything fixed and working. I thought I would share a bit, I hope it may help out in the future.

124HP RMR
8.5 grains of Accurate #7 is as hot as I went. My Springfield Hellcat 3.1″ barrel pushed 1209fps ES29 SD12, kinda on the +p side. And With 8.0 grains 1149fps ES17 SD6.

124HP RMR
5.7 grains Autocomp 1149fps ES13 SD5.
That was with the same Springfield Hellcat with 3.1″ barrel. I did go hotter but the SD’s just got to crazy with the Autocomp.

124HP RMR
6.0 grains of CFE Pistol, same Springfield Hellcat 3.1″ barrel, 1197fps ES39 SD15. Any hotter was just a waste, bullet spread just got too crazy.

124HP RMR
6.0 grains of Ramshot Silouette, Same Springfield Hellcat 3.1″ barrel, 1151fps ES27 SD11.

124HP RMR
5.4 grains of Ramshot Zip, Same Springfield Hellcat 3.1″ Barrel, 1151fps ES36 SD13.

Those are the only powders so far that I used RMR’s 9m 124HP’s that were a little on the hot side. I have done other barrel lenths that are 4″, 4.5″, and 5.2″. I listed the short barrel 3.1″ Hellcat to show that reaching the 1150fps minimum recommendation in a short barrel pistol is possible! But to continue using those rounds as practice rounds, probably not. With the Springfield Hellcat, That 8.5 grain Accurate #7 was throwing brass 3 lanes over.

In my Canik 5.2 barrel pistol, 8.5 grains of Accurate #7 was 1359fps.
