Been a while since I've been on here... We bought a new house in May and are just now getting Internet. Anyway, I was working on some hunting loads for my Garand and came across some Hornady 165gr spire points I would like to use. My Hornady manual doesn't have data for those, but does have data for 168gr BTHP. 1) Could I use the load data for the 168gr with the 165gr bullets? 2) Could I also use the same AOL for the cartridges? ***ADDENDUM*** After reading the manual a little more closely (always a good idea), it lists the OAL for the 168gr Garand load as 3.240" and the OAL for a .30-06 Springfield 165gr spire point as 3.230". Since it is and auto-loader rather than a bolt action, how much difference will 0.010" make?
