Has anyone tried R26 for the 200 grain load? I can't find any reference to R26 in the 30-06 at all but it could be a good match since it does so well in other 06 cases with heavy bullets.

Should at least equal R22 and 4831 or possibly exceed it in velocity.

RE: R22 & MRP
They well may be the same powder now. But what I gathered from internet lore and gun nut ramblings was they both started out with the same formula but got different coatings. One source claimed that R22 was a Bulk powder with up to +/-20% variation and MRP was a canister grade powder with +/- 10% variation. This could explain the kernel size variation of the older lots MRP was more carefully screened. No idea if this is fact or legend but sounds reasonable. MRP did seem more uniform lot to lot and less temperature sensitive than R22 but maybe not anymore.
