I've just started loading up my first-ever batch of 9.3 X 62 and have run into something confusing. I've got Lee shellholders and assumed that I should use the same shellholder as the 30/06 cases (this is consistent with the shellholder recommended on the Redding die box); the Lee shellholder set doesnt list the 9.3 X 62. The Graf case will go in the shellholder, but only goes in with some effort. I went thru the whole set of shellholders and the one that fits best is the same one recommended for 220 Swift, 225 Win, and 6.5 Jap. Is this the one I should use? What's up with this?

The 9.3 is a slightly larger base (about a thousandth if I recall)than the 30-06 and does not match any other standard American caliber. That is why its not best practice to neck up 3006 brass to 9.3 x 62.

The Lee #3 works for the 9.3x62

May be so, but the same shell holder that works for 243, 308, and 30-06 works fine for both Norma and Graf 9.3x62 brass.

RCBS 3, Lee 10, Lyman 2, Redding 1. All work with Norma cases.

Mike, maybe for the RCBS or Redding shellholders, but my Lee shellholder does not work well (could be just something specific to mine??).

Waxman, I tried the #3 and it worked ok, but the #10 seemed to work better, so that's what I used. Thanks to all who responded!
