6.5x284 140PT load data

[Ltsheets]

I'm looking at trying 140 partitions in my 6.5x284 for hunting. I have RL22, 4831, and Retumbo. Any of you build a load with this powder and bullet combo?

IMR 4831 or H4831??

I run retumbo with my 6.5 x284 with great results. 55-58gr.

I hear ya. I run 57gr in this gun with 140vld but didn't know with how the bullets differ if I should back off more than 1 gr on workup. Plus I won't be loading many of the partitions once a load is developed so I was thinking of saving the retumbo if others had found success with one of the other powders.

Retumbo will work, just back off a 1gr or so because of the longer bearing surface of the Partition.
