300 Win Mag
I pulled bullets from about 20 300 Win Mag cartridges that I didn't think I'd shoot, and then reloaded 17 others that I'll try and determine what provides the best grouping. I had some Hornady 165 grn Interbond and some Swift Scirocco II 165 grn bonded. So using IMR 4831 and Federal large rifle Magnum primers I loaded:
3 @ 69 grns Hornady
3@ 70.5 grns Hornady
3@ 72 grns Hornday
4@ 70.5 grns Swift
4@ 72 grns Switft
I only had the 17 primers today thus the odd numbers.
