I decided to consider reloading again. Unfortunately, it appears all the big houses are out of stock on 300 ultramag brass as well. Most other stuff is in stock.

Not sure what is going on with the 300 ultramag lately.

I've had this rifle since 1999. I haven't faced this type of outage before.

Any other 300 RUM users having trouble?

I've checked Midway, Graffs, Brownells, Cabelas, Gander, Natchez, and several others.
