I looked into using the long 38-55 but my chamber is pretty tight and I was going to have to thin the rims. The 9.3x72R brass is only .14 cents more than the long 38-55. it was worth it to buy the slightly more expensive brass than have to mess with the rims. I load for the 6.5x58R Sauer, it is one of my goto coyote guns and I use a fair number of rounds each season and have 40 made up cases. I did buy 20 Bertrams but brass in the neck is so thin that my sizing die won't take it down enough to hold a bullet and the brass is brittle from the factory and needs to be annealed before loading. I do have to anneal the 9.3x72R's before swaging to 6.5
L to R .243-6.5x58R-9.3x72R
Instead of buying two boxes of shell buy one and a set of dies and shoot it as much as you would ever want. C&H 8x58R Sauer dies are only $87.
