Velocity with gas checks?

[huntnpack]

I was given some 118 gr cast bullets with gas checks and I’m looking to load some for my .30-30. My loads I’ve put together are probably going to push them somewhere around 2200-2450 fps. Is that too fast even with gas checks? In terms of leading the barrel?

Personally I’d keep the velocity closer to 2000 if it were me. What diameter are they? If they are properly sized for your barrel, and proper hardness, then you may get by with a little over 2k, but I’d guess that 2400 is going to be pushing it

Do you know what bullet or mold it is? The Lyman cast bullet book may have some loads for it that might give you an idea of acceptable velocities.

@huntnpack, that is a nice looking rifle!

I’ll pull the few I loaded and look into a slower load. Probably with 3031. Knew I was pushing it with varget.

I just got home a bit ago and pulled out my Lyman cast bullet handbook. There’s a 115 grain Lyman bullet that’s 30 cal and uses a gas check, but it’s identified as a 30 m1 carbine bullet. Max loads for that bullet in an m1 carbine are just over 1800.
The lightest cast bullet with gas check for 30-30 is a 150 grain Lee mold. There’s a few recipes for that bullet that are shown just over 2200 fps as a max load. There’s also a note that shooters loading for marlins with micro groove rifling should keep velocities below 1600 fps and use a hard alloy for best accuracy.
