When I first began to reload for the 270 Winchester, I used JOC's famous 60.0 of H4831 and a 130 grain bullet. After putting the powder in the first case, and seeing how full it was, and realizing that the bullet would be seating on top of it, I became concerned. Called a neighbor who did quite a lot of reloading and he said not to use that much powder, because I'd blow me and the rifle both up. He used 4064 in everything he reloaded for, and I remember looking up the load he have me to try, and it was below the listed starting load for a 270.
Anyway, I finished loading my 270 rounds as I'd started, loaded the rifle up, put the rifle on one side of a tree with me behind it, and pulled the trigger. I probably killed close to 50 whitetails with that load, and never a sign of pressure. The neighbor also killed a pile of deer with his rifle and 4064 load, so it worked for him as well.
I don't mean to be surly. What does this load H 4831 have to do with 4320 *** other than the discrepancy between loading data.
Again not to be nitpicking but JOC's load was NOT with ***
H 4831*** he was using SURPLUS 4831. That powder was LEFT OVER from WWII. I shot POUNDS of surplus 4831 AT 62 grains. YES you can get it in a 270 case.
Later Hodgdon's began PRODUCING H 4831 and it went thru some (at least 2-3) manufacturing changes.
Seriously I'm only trying to prevent or clear up any confusion.
No offense at all.
