I have a few pounds of MRP powder I would like to use in my 30-06 AI with 180gr bullets. Data is a bit scarce out there. Anyone have any information they would like to share?

Thanks

I have two sources one calls the range from 54-62 grs the other 56-65 grs. I have no first hand info for the 06AI and MRP.

I used to use MRP all the time. Thenthe supply dried up. Early RL22 I found several grains hotter. The last two Lots I used was pretty much a 1 for 1 swap to my old MRP data both accuracy and velocity.

I've gotten excellent velocity with R22 and 180's in my AI, but you should just work up and see what your rifle likes.
