I tried a box of .300 Win Mag factory ammunition—Berger brand match grade 215 hybrid OTM ammunition in a new rifle bc I didn't have time to work up a load. It shot really well. I'd like to reload this round and use it as a starting point. The main thing I'd like to know is what powder is used? I believe I can reverse engineer the rest of it. as I ask that question I give the disclaimer that any reply would be taken as a suggestion and would be carefully consulted against manuals. I'm not going to blindly reload based on a reply from the internet. If anyone has done this or is familiar w powder to give their opinion I would appreciate it.
