I have some .381 GC bullets for another rifle that I'm wondering if they can be sized down to use in a .376 groove rifle or is that feasible?

You can size them down, but you will loose some of the capacity in the lube grooves.

What size ?
Just size them base first. Otherwise you could maybe strip off the gas check.
I HATE auto-correct
Happiness is a Warm GUN & more ammo to shoot in it.

I have a .379 die Lyman ?
.381 - .379 is doable (.002) but if these are commercial hard cast they may take some force to size. A push thru die used in a reloading press would be best for this, more leverage, pushes on bottom of bullet instead of nose. And allows bullet to center better.
If you are using a smokeless powder load you can size them and then use a coating lube like Lees Liquid Alox. I use it a lot. Don'e reall know what bullet it is. MY 38-55 GC bullet is the Lyman that weighs 264 gr with #2 alloy.
