375 Ruger

[High Desert Hunter]

Wondering if a .377 or a .378 will be the better size for my 375 Ruger? Still trying to decide on the mold, but I like to be prepared.

Measure the throat and buy a mould based on that.

I've done fine with .377 myself. I will tell you .379 is way too large for the throat on mine. The RCBS 37-250-FN GC is a decent boolit.
Size based on your throat for good alignment.

Thank you gents!
