243 wssm loading question.

[steelwkr]

Does anyone have any reloading information for the 243 wssm using imr powders? imr does not have any data for this caliber in their new reloading book. somebody suggested using 4064, but i don't even know where to start. i am using nosler 95 gr bt's. any info would be great!!

Ive got a box of 120gr partitions and 3 boxes of sierra bullets I need to use up.

IMR's web site has the 25WSSM now:

As for the 243WSSM and IMR powders, Hornady's Sixth lists I4350 and I4831 for 95-100 gr bullets.
