Anyone loading RMR 124 gr Nuke to +P or +P+?

[jpconstableiii]

Curious if anyone has loaded them hotter and how they preformed.

[Thad]

I haven’t tried the 124’s but have loaded the 115 nukes at the higher end of the scale and they work exceptionally well.

Thanks for the reply!

I’ll probably use most of these in a carbine so needed some actual hands on experience to understand how they hold together at over the velocity stated for reliable expansion.

The Nuke is my favorite 9mm bullet- I can’t imagine buying anything else after over a year of using them.

Now for the .45 AC Nuke to be released…

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.

Any link to a video of the 124 Nuke in gelatin?

[vkhrealboy]

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

My current+p loads with the 124 nuke is 5.5gr of N340 @1200fps. Shoots great

You do know that there is no such thing as +P+ according to SAMMI.

5.0gr of HP38/W231, 1.060″ COAL, light crimp (.003″) with Lee’s Factory crimp die.

1210 – 1230 fps out of a 4.9″ barrel. Decent accuracy.

6.4 of Win572 1.25 OAL out of a 3.8 barrel, Hellcat RDP with a 20 pound spring, NEW RMI cases
low 1272 high 1286. occasionally 1250 1260. I think due to plus or minus .1 error rate of scale.

5.8 Barrel in a G34 KKM
1354 1381 using 24 pound spring and a shell shock case. Those cases will add 10 to 20fps over a brass case. Guns are worked hard at these speeds

Primers and head expansion good. Dont do this unless you understand the powder and have good case coverage. I would not use a once fired case. Always start low and work up, what works for one gun may not work in another. You’ll get a strong push, both guns are compensated and still using heavy springs. I would not in anything 3.5 or lower barrel.
Understand Winchester 572 powder, research the competition guys who have tried it out. Is OAL sensitive and temperature sensitive. Higher FPS lower temps.
To add, both barrels were throat reamed to accept that OAL, Nuke is a fat bullet, dont load this amount at shorter lengths.

+P+ = Anything over +P is my take. The only powder that scares me that I can think of off hand is Titegroup when loading imaginary +P+ loads. There are many 9mm compressed loads out there. If someone told me they loaded 9mm to the top with Titegroup, he’d have to find someone else to try it out for him….LOL.

Any COL for this load?

[MSwickard]

Finally loaded up the 124 gr Nukes. I tested the loads in the following pistols:

Gen 4 Glock 26
Gen 4 Glock 19
Gen 5 Glock 45
Sig P226 Navy

due to the various chambers, loads were loaded to an OAL of 1.060″. Brass used was mixed. Primer used was Federal SP mag. Powder was Silhouette.

Powder charges:
5.5 gr
5,7 gr
6.0 gr

Velocity ranges for each pistol:

G26 1109-1176 fps
G19 1148-1222 fps
G45 1114-1187 fps
P226 1129-1189 fps

Best loads are the 5.7 and 6.0, but still need to do further accuracy testing
