A verry simple question.....what is the correct bullet diameter for the 38-55 Winchester?

I don't know that the word "correct" even applies... there are rifle barrels out there that take anywhere between .376" and as large as .382", depending on maker. The guys I know typically shoot .378" or .379"...

I presume you are talking about a cast bullet?

I'm toying with the idea of purchasing a new Model 94 in 38-55.....and thank you....I'd be interewsted in using a jacketed bullet.

There is no exact bullet diameter for this old round. Just remember this cartridge is a true .38 it is not a .375.
They vary from .377 to .382. Tis a fact of life.
Mine is .380 on the button. You need to slug the bore to know.

My .375 Marlin (1981) measures .3778 and it is supposed to be a .375.

I would not count on a jacketed bullet unless your are lucky.
