I would like to find out the process for making 7-30 waters brass from 375 win brass.
As it is suppose to be stronger than 30-30 brass.

307 brass would be a better/easier way to start...

but either would be MUCH heavier brass

Don't think .307 is the same brass as the 7-30 or .30/30 is based on.

307 win has the same base size as the 308 WCF.
Too big for the 7-30 Waters.

You can make 300 savage rimmed using the 307 brass. That's about all I found for using the strong 307 case other than for 307's.

[QUOTE]307 brass would be a better/easier way to start... Yes, but it is too big around for the 7/30 Waters... That's a .30.30 size case.

If you ever need to make 307 Brass, you can use 444
Marlin.

Hylander, I run the 375 Win brass through a 30-30 die backed off enough to form the neck to the same length as the 7-30, then full length size in a 7-30 Waters die, you might want to debur inside and out first. Hope this helps some,

I think the best way to get good 7-30 brass is to buy it from Federal. It lasts well, is much stronger than .30-30 brass, and is much easier than making it from .375 Win.

I made several hundred 7-30 cases from 375 win brass recently. I had very good results using imperial sizing wax and just runing them into a 7-30 die. I have been told that some people run them into a 30 herrett size and trim die first. I did not find this step needed. check the neck thickness. needs a couple of thousand's clearence to release the bullet. I did have excellent results with this brass.
