25 saum
Hello everyone,
I'm new to this forum and I'm looking for reloading data for my new gun being built. It is a 25saum(necked down 7mm short action ultra mag). I was going to have a 257STW built, but gunsmith talked me out it. Short barrel life on the STW, around 300 rounds. If anybody knows of some data, please help me out.
Thanks,
