The Berry's 124 TCFP Hollow Point Target bullets are my fav and I load a bunch of them when I can get them. I'm a bit surprised that you have to go to 1.05 to get them to fit. I also run HS-6 with a COAL of 1.125 and those run great in three different firearms, not that yours should too. But I came up with that number after a lot of testing.

Just a note that a cartridge gauge may not work with a truncated cone bullet, the shoulder can hang up in the gauge and give you a false reading.

Also with the FCD, a light touch on that is usually better but it will take some testing to figure that out.
 
Set the loaded 50 aside for now.

At 1.05", your seating depth will be close enough to the Hodgdon load for the Hornady 124 XTP. Take some new cases, use their 5.6 gr starting load and work up 0.1 gr at a time. There is a good chance you will find you can"save" the 50 loaded rounds. They will likely be a little hotter than what you use for a regular target round with that bullet.
 
Howdy from Kentucky. Welcome to reloading and THR. I can't offer any advice as I am not into loading 9mm. You wouldnt happen to have another 9mm chambered firearm that you could try them in? One with with a longer throat. That'd be a way to rid yourself of them 50.

Howdy from the Mitten State, and thank you. No I don’t have another 9mm firearm, the only other pistol I have is a 380.
 
I checked my journal and this is what I got with the RMR 124 JHP. See the bottom entry for Mar 2021.
I chronographed these in my SCCY CPx2 and my Ruger PC carbine. Since barrel lengths are similar I expect the G3c would chrono about the same as the CPx2.
Again, I am not recommending this load as it is definitely over max. But I would recommend labeling and setting those 50 rounds aside, then working up a new ladder starting at 5.1gr using your chosen seating depth and working up 1/10th gr at a time. . If you find a load you're happy with before you get to 6.0gr, then pull those 50 bullets and re-load them. If you end up getting safely to 6.0gr with no pressure signs and you like that load, then I would just run them back through the seating die to re-set the depth.
Unquestionably, the safest bet would be just pull the bullets and start over, but it may or may not be necessary.

Welcome to THR.

Berry's Manufacturing advertises 9mm 124 gr Target Hollow Point bullets sized as .356" - https://www.berrysmfg.com/product/bp-9mm-356-124gr-thp

Under "Loading Tips" tab, following information is provided:
  • Cartridge OAL: 1.060"
  • Cast or jacketed data with the same grain weight and profile will work with our bullets

When I conduct load development for a new bullet, if I can't find load data for specific bullet type and OAL/COL (bullet seating depth), I will reference all available published load data and use the most conservative load data for my initial powder work up as you can always go higher.

NOTE: Most 9mm lead/coated lead/plated/jacketed bullets can vary around 1.0 gr in weight so I interchange load data for 124 and 125 gr bullets.


Here's Hodgdon's lead load data - https://www.hodgdonreloading.com/reloading-data-center
  • 9mm 125 gr Lead Cone Nose HS-6 Dia. 0.356" COL 1.125" Start 5.9 gr (1,023 fps) - Max 6.6 gr (1,124 fps)
Here's Speer lead load data - https://reloadingdata.speer.com/downloads/speer/reloading-pdfs/handgun/9mm_Luger_125.pdf
  • 9mm 125 gr Lead Round Nose HS-6 Dia. 0.356" COL 1.130" Start 5.1 gr (913 fps) - Max 5.5 gr (993 fps)
Here's Hodgdon's jacketed load data (BTW, HAP is same as XTP bullet but without the expansion cuts):
  • 9mm 124 gr Hornady XTP HS-6 Dia. 0.355" COL 1.060" Start 5.6 gr (1,050 fps) - Max 6.1 gr (1,136 fps)
  • 9mm 125 gr Hornady HAP HS-6 Dia. 0.356" COL 1.069" Start 4.5 gr (865 fps) - Max 5.1 gr (971 fps)

Please note that while lead load data usually list lower start/max charges than jacketed load data but that's for the same bullet nose profile producing similar bullet seating depth. Hollow point nose profile that gets seated to deeper depth will often list lower start/max charges than round nose.

Since you are using Berry's plated hollow point bullet (.356" diameter) with 1.040" COL, jacketed load data for Hornady XTP/HAP (.355"/.356" diameter) with 1.060"/1.069" COL provide more conservative load data for your initial powder work up.

So you can reference the most conservative load data for .356" sized HAP at 1.069" COL and start out at 4.5 gr for your powder work up. I found HS-6 (which is relatively slower burning powder compared to W231/HP-38 and faster powders) tends to burn more cleaner and produce optimal accuracy at high to near max load data so once you determine the powder charge that reliably cycle the slide and extract/eject the spent cases, incrementally increase the powder charge by .1-.2 gr while monitoring accuracy trend.

@bigcountry5150, confused yet? What I gleaned from the published HS-6 data for the 124 XTP is at 1.060”COL and 5.6gr, it was moving either 1000 (Hornady) or 1050 (Hodgdon). Now, it’s very possible they didn’t use the same test setup, and different than your gun, but, the fact they’re so close is a good thing. Set the 50 aside and load some new 5 shot loads working your way up. Okay, 3 shot loads if you don’t have a lot of primers. You won’t get a statistically significant group size from these but you’ll see how they fire and print on paper. Good luck and let us know!
 
Ok y’all, here’s the update. I ended up getting a bullet puller and pulling the made rounds. I figured I’d just start over. I set the COL to 1.04, and used the XTP starting charge of 5.6gr as advised, and all of them chambered and fired with no issues. I don’t have a chrono, that’s on the agenda to get, so I can’t give you the exact data, but I felt like they fired just fine. Thank you to all of you who took the time to respond and give me some advice, I’m just starting to get in to reloading, and while I’ve made some newbie mistakes, I’ve definitely learned some lessons from them, and the advice I’ve received here, and will take any advice I can get, as I’m learning that while it can be very challenging just starting out, I definitely love doing it.

There is a different between handloader and reloader.

One cares about every detail of reloading and chrons everything.

The other care about making boolots and lots of it.

Excellent! Good call pulling those 50. Next thing to do is start building your personal loading data book. Chapter One: Order of Operations Is Essential! ;)
