I don’t know about the 75’s, but it seemed like the 80’s liked to be run hard with h4350 in order to group the best, even above hornady’s max load which seemed conservative based on traditional pressure signs. I loaded a bit longer than Hornady’s load, 2.750 from memory. But keep in mind the Peterson brass publication which supports hornady’s max load data for SAAMI max pressure loads.

Copy yea I was running them with H4350 over Hornady book max. I didn’t hit pressure yet but got them up to 3460. At 100 yards They should shoot a few shots tight together and then random flyer that was 1 inch away. When I shoot the 80.5 Berger’s they all stack in there together
