I used 2 loads in mine that shot to the 9.3x57 M46 factory sights.

My dies were FL Hornady dies, adjusted to only size down to the shoulder without touching it, as my rifle had .019" headspace on 8x57 RP brass. I first had to expand my brass straight - 1 pass over a plug, then sized back to a crush fit in the Hornady dies - no annealing - still haven't annealed after 3 sots per case. No splits. Probably need it now.

I worked up to these loads from slightly below. Note that on the case expansion ring, both of these loads showed absolutely ZERO case expansion when using newly formed brass - that is important and it shows the pressure for the above loads was very low & that the walls of my chamber are quite snug - just overly long.

Due to the groove diameter in my barrel being oversize at .370" and the chamber not allowing any bullets larger than .367", I did not shoot cast bullets in it.

loads:

270 Speer: 48.0gr. H4895 - 2,268fps Av. - moose 200yards was an easy shot - bullet striking about 3" below point the of aim. This load shot into 2" with the factory iron sights at 100 METERS and was approximately 2" high.

270Speer: 52gr. BLC2 - 2,300fps also shot to the sights at 50 yards.

Note, I filed out the rear sight to a shallow V - Express sight type as my eyes can no longer handle a U or narrow V sight- nothing but fuzz. The shallow V with a bead front sight works well for mw.
