So I'm getting things together to load for a 7mm-Mag. I have some IMR-4350 and an old(er) unopened cardboard can of 4831. It is packaged by Hodgdon and the price tag says it cost $2.69...
My Hornady 3rd edition lists IMR-4831 as providing the best accuracy over the range of tested bullets in the 7mm.
I'm thinking of using the Hornady 162gr SST, if I can find some.
Any guesses as to how far off the H-4831 is to the IMR-4831 listed in the 29 year old manual? Starting load for a 162gr BT is 54.6grs up to a max of 62.4grs. I'll cross reference the numbers with Hodgdon's online reloading data center before I start.
Assuming the 4831 is still good, has anyone here used it for the 7mm?
I'm open to other suggestions but I'd really like to trim the powder selections I have vice adding another (although RL 22 looks tempting...).
