.375 Winchester formed from 30-30 brass can be loaded to 30-30 pressure levels 38k CUP as opposed to 52k CUP for .375

Checked my notes and in my ruger #2 or is it #4?

I am using reformed 30-30 brass and 280 gr. cast gc bullets at 1800 fps in my #3 with the #1 stock. If you are shooting cast bullets reformed 30-30 cases should not be an issue. If you want full blls to the wall jacketed 375 Win. loads 30-30 brass will have a real short life. 30-30 brass at 38,000 CUP will get you to 2300 fps with 200 gr jacketed and 2100 fps with 220's. Hate to admit it, but I have a good bit of 375 win. brass that I reformed to 357 Herrett 30 years ago.

Sixgun has been using 30/30 for years and says no problems.

When I first got my .375 Winchester, I decided to weigh a bunch of 30-30 cases and a bunch of .375 Winchester cases. There was an overlap. The lightest .375 cases were lighter than the heaviest 30-30 cases.

The average for about 30 of each was 5% different. The 30-30 being 5% lighter (on average) than the .375 cases. Having worked in metal manufacturing plants before, I believe that they were probably shooting for the same weight, but the 5% was within acceptable tolerances.

For that reason, I would doubt that the 30-30 brass is half the strength of the .375 brass. I can readily believe that holding the reformed 30-30 brass to 30-30 pressures would be safe, but I don't know if it is absolutely necessary. Keep in mind, I have never done it, though.

there IS a difference. Big enough to make a difference? I don't know. I load the .38-55 (which sectioned looks just like the .30-30) to 2000 fps with the 255 gr. bullets without problems. http://shootingwithhobie.blogspot.com/search?q=38-55

Have 38/55 Winchester brass

by Bud, Tuesday, January 27, 2015, 10:58 (3529 days ago) @ Hobie

that is 2.085 length...375Win. Also have some Jamison that is abit longer but not consistent. I finally had to get the Starline 2.125 brass for my Marlin 38/55 due to the thin necks while using .380 paperpatched CB...that only thing that'll work in this rifle. I shoot the 2.085 brass in my #3 and Win '94. Most folks don't want 375Win brass headstamped 38-55 but if you don't care, I have several hundred that I can part with.

Have 38/55 Winchester brass...Thank you...

BUT I just got 200 30-30 Winchester brass and my friend who is mechanically inclided made an expander die to move them to 375 dimentions and then anneals them...gets many many loades at moderate levels using RL-7 powder...and 250 gr cast bullets...I am having a die made for 215-220 gr cast bullets and he will cast for me...great bullets with gas checks...so can run 2000-2100 range and keep pressure and leading to nothing....his other loads do not lead in my 41, 44, and 45s.....he is poart alchemist....thanks much....I had read where Starline was making 375 win brass this year...but could not get a definite time from them.....
