With a 52gr Sierra Match-King, QL suggests a max load of 56gr H-4831 for ~3800fps, out of a 24" barrel. As always, back of 10% for a starting load. Don't expect to find a lot in the way of published or documented load data for this cartridge, or a long barrel life, as this round is seriously over-bore. Powders with a burn rate equal to, or slower than, 4350 will give best results. Keep the barrel clean and allow plenty of time between shots, so it can cool adequately. This is a serious handloaders cartridge and highly specialized, at that. It could be fun to work with but you might consider a new barrel in a more common cartridge, like a 270 Winchester or even 35 Whelen, where you can buy factory ammo or obtain a good deal of documented reloading information.
