Easy to load for, RL17 is generally considered to be the speed king, but has been unobtanium lately. It’s not magic, but it’s a reasonable way to pick up 125 fps or to run 350 grain bullets at decent speed. In currently available powders, Big Game is probably the easiest option.
I wouldn’t buy one deliberately for the cartridge, but I’d buy a quality classic rifle in the caliber without hesitation.
