[QUOTE="mrultramag, post: 82592, member: 4467"] There are a ton of loads out there for the 300 ultra. It seems the most popular for hunting rifles depend on Retumbo or RL 25 for powder. Educate yourself on max loads for the 300 and drop 10% for starting loads. Get a good Chrono and start working up your load watching for pressure signs as you increase your charges. Beware if you are getting 100 to 200 fps more than anyone else similiarly equipped. You may be too hot. On the Rem brass, loads too warm will usually loosen primer pockets real fast. The Rem ejector will make its mark known on the case head too; but this is not all that reliable. I've had factory loads do this before. [/QUOTE]
