38.55 / 375 Win question for Tim and others

[DC]

Some time ago you wrote about shooting 375 Win cartridges in your 38-55.  I understand that a newer NEF with the smaller bore will do this sucessfully.  Are there any issues with pressure or accuracy. 
Being able to do it sure expands the usefulness of the rifle and makes it great deer / bear gun.

That's all I've shot in my 38-55, using Starline long brass and 375 Win equivilent data, but not in 375 Win brass, it's quite a bit thicker in the wall, too thick to chamber .380" cast bullets without neck turning or reaming the chamber neck. The 375 Win is rated at 52kcup, same as the 35 Whelen, a factory chambered offering, but the 375Win has a smaller case head, so it's safe, just make sure no one chambers a 38-55 round loaded to that level in any other 38-55 chambered rifle! As far as loading to 375 Win levels in 38-55 or even 30-30 brass, read the posts by Marshall Stanton of Beartooth Bullets below. I should also mention that Ian (Haywire Haywood) has a 375 Win chambered Handi that was rechambered and rebored from a 223 barrel, IIRC, by Wayne York.

I assume then that going the other way, shooting  a 38-55 in a 375 is no problem. Correct?

Only if you trim the 38-55 brass as stated by Marshall in the link I posted, the 375 Win chamber is shorter.

I have a Hi-wall (1893) Winchester, and a .375 Marlin I've been interchanging brass in for some time with no problems.
You know what they always say about dumb luck, apparently my Marlin is chambered deep.
I've been using 29 gr. of reloader7 and 250 gr. JFPs, and getting good accuracy out of both rifles.
I don't feed the Hi-wall too many of these rounds, but it's nice to know that I can.
I got a bunch of blown out .30-30 brass from a guy, and that's all I use now because it's short enough to fit in everything.
Next to .45/70, .38-55 is my favorite. And IMHO, the .375 Marlin is one of the most gracefull, best balanced rifles ever made.
