I am screwing on a 6.5 creedmore to my surgeon in the near furture and wanted to see if I could get some advice on starting points for load development.
That's a great place to start as it's the load on the factory 140 AMAX load. 44.5grns of H4350 and the 120 AMAX was the original 120 load but they have since gone to Varget to lighten recoil some. H4350 is a great powder for the Creedmoor.
Here's a link to a couple threads in the Reloading Depot with Creedmoor loads.
