I have been using 42.5 grains of 4064 with a rem 9.5 primer and 180 Nosler Partition in my little Win. 70 Classic Compact short action for years.

I like this load because I can buy Partition 2nds on sale for about $13.50 for 50 bullets.

This isn't a super fast load. It isn't a super accurate load. But I don't care. It has taken a considerable number of whitetail bucks at under 200 yards - most with 1 shot and flop dead right there.
