eabco.com is chambering it. Used dies in a low demand like this one is a long shot. eabco has an arrangement with Redding, I think. Might be of some help. Huntington.com has the RCBS custom shop. Expensive. ch4d.com is usually much cheaper. Mr. Ackley wrote that in a sturdy rifle (NOT a Krag), it could equal the preformance of the factory .300 H&H Mag ammunition. Of course, .300 H&H was held down for use in Africa and other hot places... just a little. Lee does a run of odd ball calibers once in a while. Might check there. LUCK.
