Home Forums Hunting & Shooting Custom Rifles & Wildcats Remington 721 375/300

I picked up a Remington 721 rebarreled in 375/300, which is a 300 Winchester Magnum brass necked to take a 375 bullet. It came with a set of Redding neck sizing dies and loading dies which I guess would’ve had to been custom ordered. It should make a great gun for anything on the North American continent. I have found little to no info searching forums on the cf and others about this cartridge and would like to know a little about it. If any of you gentlemen know anything about this cartridge please feel free to share your knowledge. If it matters at all, the gentleman I bought it from claimed it came from out west. With that said, it maybe something common out that way so y’all chime in. Thanks!

Sounds like the .375 Epstein (an no - he didn't kill himself) There's an article on it in Wildcats Vol 1 & 2 put out by Wolfe Publishing. I may be able to dredge it up.

Check out 375 Taylor. Probably all the info. you need.

Brass is easy to make .....

Classic old rifle. Great wildcat round. You are set to reload so go have fun. In the field it will be the equal of any other 375 meaning it will just work.

Those photos are great, I didn’t realize there was that many 300 variants. Thanks Swamplord

It definitely will, it won’t out do any of my 375 h&h’s but it’s something different and interesting
