Help with 9mm 125 gr. LTC

[Cortland]

Alright, so I bought 1,000 9mm 125 gr. LTC bullets. I've found data in the Hodgdon manual for 9mm 125 gr. LCN (which I assumed was the same as LTC) but with an OAL of 1.25". For the bullets I've got, that OAL doesn't even put the lube groove below the case mouth.

Because of the contour of the bullet, in order to get the rounds to chamber I have to seat the bullet at 0.970". I have found some 9mm LTC load data in a Lyman manual but that gives an OAL of 1.061" which is still too long. I've always heard 9mm is very sensitive to seating depth which is why I'm hesitant here.

Any suggestions for load data? Do you think I'd be safe to load a few using the Lyman starting data and then chrono them?

Thanks.

That's a terribly short OAL, I looked in the Speer #12 and most are loaded to 1.12" and 1.13". Looking in the current Hodgdon loading book the 9mm 125gr LCN (conical) is loaded to 1.125".



I wouldn't even want to try one at less than 1"!

Stupid question but what does LCN and LTC stand for?

I have some new 9mm lead bullets that say RCBB. They are round nose and I am trying to figure up a load for them too.

Lead Conical Nose and Lead Truncated Cone I think- but im not positive

Because of the contour of the bullet, in order to get the rounds to chamber I have to seat the bullet at 0.970".

Assuming LTC is Lead Truncated Cone, then .970 is extremely short. I load 125 Gr. TrFP's (Truncated Flat Points - Same thing) at 1.060 and they feed in everything I have.

That's .090 deeper in the case. Quite a bit for a high pressure round like the 9MM.

Double check yourself on this. If you just ABSOLUTELY have to load them this short for them to feed I would suggest starting a bit below start loads from your manual. Say 10% below.
