Any of you guys reload for 8mm lebel?

I load for my 86/93 Lebel with "Balle N" chamber.

Lee dies
.348 Win. or Graf/Prvi brass.
.323" bullets (though .327", like Balle N, might be better)

I found published data generally over-conservative, eventually settling on 48-49 grains of non-cannister (surplus) IMR4895 with the Sierra 175 spitzer for a MV of ~2550 fps with decent 100-yard groups from a pretty dark bore. Since this was with a non-cannister lot of powder, this charge can't be applied safely to cannister-grade 4895.

Below information consists of software estimates from QuickLOAD set for a maximum average pressure of 50,000 psi (CIP piezo). Estimated velocities appear substantially higher than what I chronographed with my non-cannister 4895 loads. Note that this listing is merely of estimates and doesn't represent tested load data!

Cartridge          : 8 mm Lebel M/93 (8x50R)
Bullet             : .323, 175, Sierra SP 2410
Cartridge O.A.L. L6: 2.808 inch or 71.33 mm
Barrel Length      : 31.5 inch or 800.1 mm

Predicted Data for Indicated Charges of the Following Powders.

Matching Maximum Pressure: 50000 psi, or 344 MPa

C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet and gun.
USE ONLY FOR COMPARISON !
