I also use Hro0nady dies, both 9.3x62 and 9.3x57. I use a set of Hornady .375 Styer dies for neck sizing and seating bullets in my .375/06IMP as CH4D would not make the dies to my chamber (supplied cases - TWICE) They kept insisting on using a .454" shoulder as that is normal for Ackley IMP standard cases, which oversized my .460" shoulder.

My 9,3x62 liked BLC2, while the 9.3x57 likes both BLC2 and H4895.

My .375/06IMP has exactly the same case capacity as the 9.3x62, at 78.0gr. in RP and FED cases. WW cases have 80gr. capacity.

This rifle also likes H4895 & BLC2. There are a whack of other powders they like, as in RE#15, IMR4064 and IMR3031.
I think those are .450 Alaskan's in the loading tray beside my 9.3x57 Husky.

270gr Speer - 2,300fps MV- impact at 200 yards, bullet blew up and wrecked most of the onside leg. Fragments hit the lungs- lucky for me. The impact velocity was about 1,850fps, maybe. it did hit the leg bone which is a good 2" in diameter, smashing out 2 1/2" of it's length & going to pieces doing this. This is not a lightly boned deer leg, but at the velocity the bullet was going, I was surprised it blew up.
