I have been reloading 115gr Berry FMJs for a long time at 4.5gr of Titegroup. Reading posts here it seems most people are loading 9mm with less than 4gr of Titegroup. I tested my compensated HK P30L with different amounts of Titegroup and I only stopped seeing failures to eject or feed when I reached 4.5gr and above. Is it abnormal for 4.5gr to be needed for reliable function?
For reference, out of 10 rounds each:
4.2gr: 3FTE, 2FTF
4.4gr: 2FTE, slide did not lock back on last round fired
4.5gr: 0 malfunctions
4.6gr: 0 malfunctions
I also once had a round stuck in the barrel when I was loading with lower charges. Any explanation for this?

That’s pretty strange… I load for that EXACT SAME GUN using the same combo with 4.0gr.

Yeah that seems like a lot…my boss/reloading buddy uses 4.0 grains of Titegroup for 115s, and they cycle my Canik just fine, and it’s NOTORIOUS for needing NATO pressure loads…any chance your scale is either calibrated incorrectly, or the batteries are low and giving you a false weight? What scale are you using?

I don’t have my books handy but 4.6 gr has to be close to or over max charge right? I load at 3.9 for a cast bullet that comes in around 118 gr

I shoot TG 4.5 Berrys 115 plated RN, no failure to feed after 4.2, just liked 4.5 much better. I’ve shot thousands through Stribog, PC Charger (had the most issues with failed to eject at 4.0-4.2) HK VP9, Springfield XDE and XDs, and canik TP9SFX and TP9 Elite SC. Some failures on the caniks at 4.0 (1 in 20ish if I recall). Everything loves 4.5. OAL is 1.13-1.135

I’ve been using 4.3gr with 115s because I had some stovepipes with lighter loads on a comped P80 G19 (even with a lighter recoil spring). The 4gr loads ran fine in my G43. I just figured the comped guns like hotter loads.

My Hudson didnt cycle right until I hit 4.2gr. My cousin’s glock loves them too.

4.2gr Titegroup with 115gr bullet is the sweetspot in all of my CZ guns
ocabjGuestJune 15, 2021 at 8:43 am
I’m pretty sure I just use 4.4gr for 115gr in all my Glocks.
Hodgdon’s online data for a 115 JHP and Titegroup has a range of 4.5 to 4.8, and 4.3 and under for lead. At one time I might have been using 4.2gr for 115s FMJ/plated.
I’ve never had any reliability issues. Your specific gun just may need to have faster rounds in order to operate reliably.

What’s your OAL when using the 4.5g titegroup and 115s?
JJ_JJ_JJ_JJGuestJune 15, 2021 at 8:43 am
Im at 3.8gn with 115gn Xtreme RN in all my S&W’ with an OLA of 1.1.
Anything more than 3.8 I start to see primer flow
JicandGuestJune 15, 2021 at 8:43 am
Hodgdon website has 115 grain Speer hollow points listed at 4.5 grains to 4.8 grains of titegroup.
That being said, it makes sense you’re having issues when running below minimum loads.

You have a lot of responses already, but if you’re using a stock recoil spring, it’s probably too stiff. Either run a ton of hot loads through it or get a lighter one.
Firefan07GuestJune 15, 2021 at 8:43 am
My go to load is 3.7gn behind 115’s. They feed fine in my G34, P365 and carbine. I have tested down to 3.5gn with zero reliability issues.
