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

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

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.
