Home Forums Reloading Big Game Rifles Sizing .375 cup and core bullets to .366 (9,3)

Thank you! As I also have a .375 H&H, and plenty of 270 grs Hornady Interlock SP, I use them. A friend, some 1600 km from home, size a box of this down to 9,3 and the accuracy was more than good! The same as with the 286 grs Hornady Interlock 9,3 bullets. I bought 2 boxes of the 225 grs just to try to size down and use for practice in the 9,3x62 to complement the rather expensive 220 grs FOX monometalic slovenian bullets I like so much! So, I want to try sizing them to .366".
I am open to other experiences doing this.

Thank you!
