    I bought 3K of these over the Christmas sale, loaded/tested them, and have had great results! I love Power Pistol and tested up to 6grns with these bullets, and 6.4 was the max. At 6, they shot outstanding and were over 1200FPS. With Power Pistol, you know you have a load, big boom, and flash, but even at that weight, the brass/primers looked great with 0 signs of pressure or any issues. I ended up backing off to 5.8 just because. I was using once-fired Winchester brass with GINEX primers. I did most of the testing out of my Staccato P and finished up with my CZ PO-7 both run these bullets great. I have a 10-shot group @ 50ft that has one large jagged hole out of my Staccato, if I could upload it I 1would gladly share. The bottom line for the price these are very good bullets & cleanup was nothing out of the ordinary. Thanks, Jake!!

    Power Pistol is an amazing powder. Such high velocity with low chamber pressures. It’s like magic.

    I load the RMR hollow point 115 gr JHP (MPR NUKE) at 6.6gr and 1.125″ COAL. They are really powerful, but according to QuickLoad calculations still have a manageable pressure. It seems like Power Pistol burns slower than other powders (like Titegroup) to give a longer push duration from the slowly increasing pressure. Hence the big muzzle flash because all of the powder is not burned as the bullet exits the barrel. These rounds shoot incredible well out of my Staccato P, which seems to like a powerful load to cycle reliably.

    I use a lighter load for my other guns. For plinking I use 3.8gr of Titegroup (which seems to have an almost instantaneous pressure peak) with the RMR 124gr FMJ Truncated Cone Flat Point MatchWinner, but at a COAL of 1.075 to get higher velocity out of a lower cost ammo. 1.075″ COAL allows for flawless load in some pistols like a CZ which seem to need a shorter cartridge, based on bullet shape.

    As a note of caution based on my experience. Watch your COAL. The beauty of 9mm is your COAL can be varied a lot based on the bullet shape, your load, your gun requirements, and the resultant chamber pressure. But it can significantly change your chamber pressure. Seems like COAL is almost as important to watch as the actual amount of powder. Most other pistol ammo COAL has little wiggle room for a variety of reasons.

    Thanks for the input and info—good stuff. I agree that Power Pistol is a great powder, and I typically use it for my JHP loads and SHTF-type ammo. I use, test, and then stash 90% of it , LOL. I will shoot it a couple of times a year though, just for groups/fun/function testing. I was always a Universal guy for 9mm & titegroup was my 45-powder, that was in a perfect world, now I haven’t seen Universal in years, kinda weird. I bought some of the Winchester 244 a few years back and just started using that for my standard 9mm loads, I still have Titegroup but wanted to try that, seems clean & accurate so I guess I’m good with it.
    Thanks for the concern on COL,I fully understand the importance of it & other than my Staccato I have multiple CZ pistols and if ya know anything about them they have one of the shortest leads in the chamber & always base my loads on my CZ-07, if they fit/plunk/run in my 07 they will work in everything I own & I do check my other pistols just to confirm, I don’t have the OAL in front of me but it’s within safe specs for sure.
    When its all said & done I love all of the RMR bullets I have bought & used,just great bullets @ a great price.

    Does anyone have any load data for the 9MM 120 JHP nuke for tight group?

    Here is some info from the Hodgdon Website. I would start here. Jake says to use the same as with the 124 Nukes copper.
    Look here, just type in your info. I tried to copy/paste but it comes out weird, sorry bout that.

    I appreciate it. Yeah I’ve been on there already looking for data. However, they don’t have any JHP data I cross reference a couple different books and I ended up going with 4.2 tight group CCI 500 primer and an OACL of 1.083. I’m gonna go test them tomorrow hopefully. One of my books has no data for 120 grain, and my other one doesn’t have any Hodgdon recipes.

    Well, the typical formula is “smaller” weight bullets use more powder, and heavier use less so when Jake (RMR) says to use the same loading as for the 124 Nukes I would say you will be safe. BUT with that said you always start low check for pressure/function/etc to be sure. Keep us posted on how they shoot and what you’re using. The 120s shot lights out coming out of my Staccato P with a Holosun 509 mounted @ 50ft. I shot a very good group also out of my CZ PO-1 at the same distance.

    I tested some out with Titegroup last fall. COL of 1.060″, shot out of a 3.75″ barrel from a CZ P-07.

    Charge Velocity STD ES
    3.5gr 977.76 11.14 34.88
    3.7gr 1009.07 8.85 25.79
    3.9gr 1053.33 12.34 42.54

    Not bad results, but I ended up choosing CFE Pistol, as I got a bit more velocity than I could from the TG without going over book max for my reference data. Same COL and gun as the TG data, and tested on the same day.

    Charge Velocity STD ES
    4.7gr 1028.47 23.34 67.88
    4.9gr 1056.4 12.16 35.04
    5.1gr 1100.22 9.98 32.52
