38-55 vs 375 Winchester

[acmetruck1]

So can anyone explain The difference other than pressure? Seems like the 375 will fit an old 38-55 and cause issues?

Here you go, all credit due to Lyman. Look at the description paragraph on the 375 Win sheet.

Groove diameter, OAL brass trim length, OAL cartridge length, barrel twist... Lots of differences.

If your question is curiosity I get it. If you are considering shooting the obsolete 375 in a 38-55 I gotta wonder why. 38-55 is more available than 375 and a good chambering for the Midwest. If you have a load of 375, sell it on gunbroker or the like and fund proper ammo.

Yeah, just an ignorant question. So basically a .38 special vs .357 mag situation except without the size difference

No such thing as an ignorant/dumb question. That's how you learn. Exterior case dimensions for .38/.357 are basically the same except for length. Not so with 38/55 375. Completely different dimensions. Length, width and taper are totally different along with totally different bullet diameter. Hundreds and thousands of an inch make a big difference just like a combustion engine and other associated type gearing.

THANK YOU ! People are so quick to insult other members for asking questions. It's a legitimate question. Better to ask.

Not ignorant. It's a good question.

Ok, so ZERO interchangeability. I’m looking for a good vintage hunting caliber other than 45-70.
Was thinking 38-55 but then I read that the 375 was better and somehow got the idea that they were more similar. Thanks for the help. I really appreciate the info you Jedi masters share!

38-55 is an awesome caliber. You'll never go wrong with it. If you're in the least bit recoil sensitive, take the 38-55 over the 45-70 all day long.
