Expected accuracy from 458
I know this is not a long rang cartridge but I am trying to put together a good load for my 458 Win Mag. it is built on a savage action with a Douglas barrel (27").
I want to make sure that I am trying for realistic results. I am using 350grn hornady round nose, Winchester cases, Winchester mag primer, and h4895. I chose this powder because of it's low pressure ratings and it also fills the case. To date I have worked up to 78.5grn with a 1.5" group at 100 yards. The max for this powder is listed as 80grn.
Is 1.5" the best to be expected or can that be improved on? If not is there any reason to increase the powder?
smell different to midgets
