FWIW, I settled on 24.5 gr of TAC with the Hornady 62 gr BTHP as our primary load in our AR-15’s. Has been accurate in twist rate of 7”, 8”, and 9” AR’s. Might be a good starting point for you to see what your rifle prefers. Let us know how it works out.

What are you shooting them in? I would use your barrel as a chamber gauge. Start around 1.12” OAL and see if it plunks. If it fully seats in the chamber when dropped into the barrel, then see if the cartridge spins freely. If it doesn’t plunk (fully seat), then seat the bullet a little deeper, and try it again. CZ’s tend to have a short throat and tend to need a short OAL, around 1.06”. My Glocks have a longer throat and can be loaded longer. If you have to load to a shorter OAL, starting at 3.8 gr Titegroup should be okay. But if you find a longer OAL works, you might want to start a little higher, say 4.0 gr and work up from there.
See Hodgdon’s Reloading Data center and note the different OAL for different bullets and charge weights differences.

I had a similar experience recently with Fiocchi small pistol primers, mild load of True Blue (5.0 gr) and S&B brass. I have loaded 100’s of 9mm and .357 Mag with these primers previously without issue, but these were too light to function in a Glock 19 or CZ P-09. Perhaps it was a combination of colder weather (50 degrees) and lighter powder charge (Sierra No.6 max!), but I was quite surprised. In checking older Western Powder suggested starting loads, I was at least .5 of a grain under their suggested weight for True Blue and 115 gr bullets. I replaced the new factory recoil spring in my Glock 19 with the original old one (hoping it is tired after over 20 years and thousands of rounds) to see if it can run them. I may wait until summer and 100 degree temperatures to give them another try. I should have tested them with a smaller batch before I loaded 200 of them..

Update: tested my loads listed previously. Functioned fine in both a Glock 19 (15 rounds) and a CZ P-09 (5 rounds). Didn’t shoot for group on paper, but seemed plenty accurate on steel plates at 15 and 25 yards. The bores didn’t show any unusual fouling, cleaned up fine afterwords. Will try again next outing. I like them, and the price is right! Thanks, Jake.

I had a Competition Electronics Pro Chrono that I used for 15 years or so, with no problems. I upgraded to their Blue Tooth capable DLX model about 18 months ago and gave my old one with the wired remote to my son. Both of them still work quite well, probably because when using them all rounds were fired from a solid rest at least 10 feet from the chronograph. So neither of them have had bullets through them. Did you consider taking them up on their offer of repairing your damaged chronograph for 1/2 the cost of a new one? Or you could wait until Midway has another sale on them. If I recall, I got mine on my birthday special for around $110 18 months ago.

I haven’t used Silhouette yet, but I would use the data for the Nosler 115 gr JHP bullet, as it is similar to the RMR bullet. Start low and work up, watching for pressure signs.

[cbmay48]

FWIW, I seat the “pre-nuke” RMR 124 gr MPR to 1.075” to be able to plunk and spin in my CZ P-09. I run them at the same OAL for my Glock 48, although I could probably seat them longer in the Glock.

Got out today with the 124 gr RMR MPR JHP bullet loaded in front of 4.0 gr Titegroup, CCI-500 primer in a Federal case. About 60 degrees, results:
Glock 48 average velocity 1,072 fps 5 shots
CZ P-09 average velocity 1,096 fps 5 shots

Same bullet, primer and case with 5.7 gr Power Pistol
Glock 48 average velocity 1,112 fps 5 shots
CZ P-09 average velocity 1,142 fps 5 shots

RMR 115 gr FMJ, 5.6 gr CFE-Pistol, S&B small pistol primer, Winchester case
Glock 48 average velocity 1,053 fps 5 shots
CZ P-09 average velocity 1,083 fps 5 shots
Kind of expected higher velocity with the lighter bullet and CFE-Pistol.

Winchester 115 gr JHP, 5.6 gr True Blue, Federal 100 primer, Winchester case
Glock 48 average velocity 1,025 fps 5 shots
CZ P-09 average velocity 1,035 fps 5 shots
Also a little disappointing, velocity wise. This was an old batch of bullets that I paid $40 for 1,000 (shows you just how old they are!)

My conclusion is that Power Pistol is probably the top pick for performance with the 9mm, although, I may need to push True Blue and CFE-Pistol to +P levels, just to see if there is a significant boost in performance. But I was surprised with Titegroup being as close to Power Pistol as it was, and is certainly more economical. I didn’t really shot for accuracy, since I was more interested in the velocity numbers. My P-09 seemed to like the loads better than the lighter, thinner Glock (it is new and I am still getting used to it).
Hope this helps.

And still hard to find, unless you don’t mind paying over $100 per thousand online including hazmat and shipping. Sportsman’s Warehouse has decent prices when they get them (a rare event), and limits purchases to two sleeves (200) per person per day. Maybe by 2024 they might become available locally for less than $100 and with no limits on purchasing…

While I haven’t chronographed your exact load, I have run the 124 gr MPHP (pre nuke) out of a new Glock 48 with 3.6 gr of Titegroup and S&B SPP. They clocked an average of 949 fps with a Sd of 10.
According to Glock, my barrel is 4.17” long. I suspect a 4.0 gr load would top 1,000 fps, but probably under 1,100. I should try 4.0 just to see what it would do, already have 3 primer tubes full of CCI-500 primers ready and waiting on the Dillon RL-550B.

For my 26” 1 in 12” twist bolt gun: Hornady 50 gr SPSX, 26.0 gr Ramshot TAC, CCI-400 shoots under 1/2” for 5 shots from a solid rest at 100 yards. Chronographs just over 3200 FPS (the rifle is over 14 years old, but still accurate)
For AR’s Hornady 62 gr BTHP, 24.5 gr Ramshot TAC, CCI #41 or Rem 7 1/2, sub MOA, 2840 FPS out of 18” 1 in 7” twist, 3000 FPS out of 14” 1 in 8” twist barrel in warm weather. Loses about 100 FPS below freezing.
Still working on RMR 69 gr BTHP. Promising loads are 23.6 gr TAC along with 24.0 and 25.5 gr of Shooter’s World Precision Rifle, CCI #41 primers. TAC had best group of .70” at 2851 FPS, SWPR 24.0 gr posted .88” at 2732 FPS, followed by SWPR .93” at 2905 FPS. All loads used 24” barrel with 1 in 8” twist at 42 D F. Max loads would probably hit 3000 FPS above 7O D F.
