Birdhunter, I got the 9.3 x 57 dies in last week and got to load some test ammo for the rifle. I loaded in 1 gr. increments of H 4895 powder using the 285 gr. pp bullets. 42.0grs. no pressure signs- 1 3/4"
43.0 grs. no pressure signs- 17/8" 44.0 grs no pressure signs 17/8" 45.0grs very little pressure sign 1/1/2" best group so far 46.0grs 1 7/8" showing some pressure but not much. Measured case heads none varied .0002 after firing. Primers were all rounded in their pockets and were starting to flaten @ 46.0 grs. I hope to do some more testing later, I must leave it now as I am trying to make some deer and pig hunts and work as well. The above mentioned loads were shot in a Mauser mod. 98 in very good condition with zero headspace. I do not recommend any of these loads to anyone. Will post more info later. Bill439
