Used for targets.
I don't have the hornady manual for the load data. I came across a box of these and need a good target load for 500- 900 yards
I've tried both H-4350 and IMR-4064 in the 30-06 don't own a 308 but Hodgdon data should work for the 308. I read one of your earlier post about that bull you got with 30-06 made a good shot on him.
Nothing wrong with the Hornady manual but for the 30-06 but they tend to start at a lower velocity and amount of powder give you good example. for a start load using 180gr SST start load is 40.1g/IMR-4064 @ 2300fps and max is 49.2gr/IMR-4064 @ 2700fps and Hodgdon data for 180gr Sierra bullet start load 45.5gr/IMR-4064 @ 2550fps max 48.7gr @ 2700fps.
there is difference in test rifles
You use lot more bullet working up with Hornady data but they do list what rifle their using. Well good luck
