I'm hoping my 358NM shoots well with the N-204 powder and 250 gr Partitions, hoping better still that the little fixed 3X Weaver will survive it all, as I really want to use that scope on this cool old Mauser.
Looks like it should work really well Gunner. Great case fill and FPS looks pretty good as well.
