Now the big decision...115 or 124?
I'm thinking 124 for carry. Need to get some other bullets while I'm there too |

Had no idea these bullets changed
We(wife, assistant and I) have been using the MPRs for a few years for open major fodder. Stupid accurate and good pricing(always a -5% code somewhere) Ordered 21k on 4/19 and they arrived quickly. noticed the exposed lead tip was absent on this batch. Measuring oal was always slightly off as the lead tip would very slightly but not an issue for fps/accuracy for us. The new tips are MUCH more consistent on the oal. We are running 173pf with these. Thats right around 1400fps at 1.165oal and 10.2g of Shooters world major pistol powder. HOT and LOUD. 15-20y zero on the open guns produces a nice clover group with these and the comps stay lead free. I was wondering why the tip/cavity was slightly different till this thread! |

Picked up 500 124s to try out, they will be here tomorrow. Probably going to try out Blue Dot first, are people using load data for XTPs or GDHP? Also where is your OAL landing? Guess I'll find out this weekend.

Isn't it strange that the bullets we might use for self defense are the ones we probably use the least. You develop a load. Prove it is reliable in your handgun. Load up a bunch and put them away, hopefully never to be seen again. That I ordered 1,000 might mean some actual use and training with them, especially given the reasonable cost. |

Got my 124s in last week. I was using the MPR under a load of cfe pistol. I really like that the lead doesn't protrude from the nose any more, should keep the seating die cleaner and oal more consistent.
I'm going to load up a few this week and see how they do. I know with my other mpr load I'm running 1200fps. I'll probably try to match my fed HST carry loads as usual so I have a close recoil impulse. |

A K of the 124gr arrived at my doorsteps Thursday.
I've loaded the MHP's 124gr to 1168 fps at 1.075 COAL Should be easy to achieve the recommended expansion velocities. Maybe next week I load a batch and chrono |

Did a plunk test with the 124's in my CZ75. Max COL for that gun is 1.085"
The earlier MPR version had a max COL in the same gun of 1.11" Hope to load a few up this week . |

Not a real test, but something to give some idea of performance until someone does a serious test.
Loaded a few 124's with BE-86 at a little below Alliant's listed max (since I'm loading them shorter for my CZ). In CZ75 compact 3.75" barrel had a velocity of 1135 In Sig P365 3.1" barrel had a velocity of 1075. Shot into water jugs (actually empty plastic cat litter jugs) from ten feet with the Sig P365: Penetration about ten inches. Jacket completely separated from lead core. Lead core expanded in three petals to .61" Final weight of core plus jacket was 120 grains. |

An M&P Shield has a 3.1" barrel, and shooting Federal standard pressure 124 HST from my Shield I saw an average velocity of 1097 FPS. So I would guess your BE-86 load is a pretty good approximation of 124 HST. I should probably get some of these new RMR JHPs. I had just ordered a resupply of the older MPR design just a few months before the NUKE was announced. So I have a couple thousand of those in my stockpile. Bad timing on my part. |

Made a few dummies to check oal, and plunkability. MP and SIG took just about any length, I have a p80 G43 which I got these for. I could get it to plunk but it wouldn't come out easily. Pretty sure I ended up at 1.055. I loaded up a couple and I'll go light them off next week.

I have the 115 gr NUKE not the 125's.
I'm checking the bullet profile and I ended up fairly short (~1.070" OAL). It "looks" okay. You know how when something looks okay, it probably is. Is it okay? I don't think loading longer is in the cards due to how little of the bullet is inside the case (approximately 0.16" inside the case). Look closely, you'll see it ends before the midway point between the case mouth and the knurling. I could load it a little shorter to get more bullet in the case (maybe as low as 1.020" OAL). Much shorter than that and the bullet diameter starts to taper down as the ogive begins. THAT sounds bad. I checked the Sierra Manual. For 115 gr bullets, their JHP was loaded to 1.050" and the FMJ bullet was loaded to 1.100". Any thoughts on OAL for the 115gr bullet?  Taper crimp will be added after I select an OAL. The factory round is a 135 gr Federal Hydra-Shock. |

The rule of thumb is to try to get one diameter of the bullet inside the case. Plus or minus, YMMV, etc.
If you seat the bullet deeply enough that it won’t be dislodged by recoil, yet you’re not quite at “one diameter” inside the case, that’s probably not a big deal. I typically look at manuals’ LOA recommendations for bullets of the same weight and with as close as possible to the same profile. With hollow point bullets, that gets to be kind of tricky, since a really deep hollow point will give you a longer bullet for the same weight… Has RMR chimed in on this? They say they’ve used these bullets extensively… Sidebar: is RMR a member here? |

From Hogster98 on rmrs forum:
"I went out and did some shooting and reloading the last couple of weekends to try and get some data on the new RMR Nukes with CFE Pistol powder ( I bought several pounds during the great powder/primer shortage of 2020-2022): Pistol: P365 Bullet: RMR Nuke 115gr. Powder: CFE Pistol Brass: Mixed Primer: WSP (Winchester Small Pistol) OAL: 1.085 1.090 1.093 1.150 Grain: 5.8 5.8 5.8 5.7 Average fps: 1111 1068 1069 1043 Dillon 550 B Press The reason for the OAL differences is that I wanted to see if there were any feeding issues in the P365, and I had no issues with any charges or lengths within this range. I did some 5.8 gr charges at 1.085 OAL and some shots went up to 1135fps and that seems a little too hot. Oddly, if the OAL was 1.093, the 5.8gr fps rose to 1069." |

Very good, thank you. You are at least a week ahead of me in getting the testing done.
As a prelude to loading for testing, I was thinking of manually cycling some inert cartridges to ensure they feed from the magazine into the chamber. I was also planning on going the other direction on OAL - shorter, like 1.050" per the Sierra manual. I need to check on various reloading guides for OAL. |

I asked RMR about this.
Me: Any insight on how deep to seat these bullets (both the 115gr and 124gr)? You indicate on the product page that these are an outgrowth of your MPR bullets, and cite some very impressive penetration data. Can you share your preferred loads with these bullets? RMR: That’s gonna depend on your gun. My guns like 1.12” but there’s lots of guns that don’t allow that long. Newer glocks and CZs sometimes only let you get to 1.06” Me: Mind if I share this on the AR15.com reloading forum? RMR: That’s fine. There’s just so much variance in chambers that what works for some won’t work well for others. Handloaders shouldn’t be stuck with just the minimum OAL for every gun. I like mine loaded out pretty long but with all the new short chambered guns my loads won’t work. What I get out of this is that the LOA you load should work with your gun, period. That presupposes you work the load up so that your gun doesn’t blow up because you had to load kinda short to feed your CZ.. |

I’ve found the the Apex barrel I have in my M&P has the shortest throat out of my 9mm guns, so all reloads have to fit it. I’ve also determined that the best accuracy in the M&P is for the loads to be .003”-.005” off the lands (max plunk). The rest of my guns seem to like what the M&P likes, so it works out!
The older 124 MPR, the 124 Match winner and the 147 match winner are all loaded to 1.080” for my guns. ZA |

I haven't loaded pistol rounds in a long time. I'd forgotten the feel of it. That I'm using nickel plated brass made it just that much more strange. It was harder than I remember, so I ran some brass cases thru for comparison. Nickel plated was more difficult.
I loaded up 10 rounds each at 4.5, 4.8 and 5.1 gr of W231, all with Winchester SP primers and all at 1.050" OAL and using a taper crimp. Remember, mine are the 115 gr variety. They look just fine. I'm interested to test but have to wait a while (weeks) to get out to the range. I'm primarily interested in reliability, reliability, reliability but will also get POI, group sizes and chrono data. |

Getting back on topic - sorry for contributing to the derail - has anyone developed any loads for the OLD “MPR” bullets and seen how that data works with the Nuke bullets?
Since the weights are the same, and (apparently) the bearing length of the Nuke bullets seems pretty darn close to the MPRs, I’m curious to learn if you get different velocities with the newer bullet design. |

I loaded mine to similar OAL and powder charges as the MPR. I did lower powder charges just to make sure. Accuracy was not there so I will probably have to move the COL in even more. 1.07” and 5.1gr CFE pistol was great out of the 124gr MPR it I might have to move in to 1.06” |

How do you guys accuracy test your pistol rounds?
Benched? Sand bagged? Offhand (bullseye style)? What distance? What target? I'll be doing that with these loads soon. It might be nice to have a common method so we can compare group sizes. |
