None of the manulas I have show the 123gr Amax.They have 120gr and 125gr bullets but not the 123gr and the 120 and 125gr data is way different. If anyone has a manual with .260rem 123gr Hornady Amax with H4350 powder please post the min and max loads thanks.

I can't imagine that 2gr makes a huge difference in bullet weight. Seems like you could use the 125gr data, back off 10% and work up.
