Just want to triple check a charge I'm using:

Shooting a "Turked" Gew 88 Commission rifle with

175 gr. cast round nose/gas checked over 18 grs. of Alliant 2400.

My Lyman cast bullet manual doesn't list 2400 but I checked in a bunch of places and it seems a safe load. I shot Remington 170 gr. commercial as well as a bunch of 175 cast over 16 gr. of 2400 I made; no problems. Thought I'd take it up a bit and see what the target looks like.

I'm still a bit of a novice at this, so I figured, "what could it hurt to triple check the load with the folks who know?"

thanks in advance.
