[grizzlybeardavid]

Anyone have any reloading data on the 250 Partition? Am going for Elk
and want to start load developing this spring.

Our #5 guide starts

IMR4350 77.5grains @2686fps

IMR7828 84.5grains @2688fps


These are starting loads for a 358 STA 250grain PT

My 358STA has a slightly streched body so I would reduce my load slightly to start. It is 93gr of H4831 with a 250. Most of the 358STA's (standard chamber) I've built for friends have either liked H4831 or IMR4350 but all of my friends shoot 225's.
