Home Forums Reloading Big Game Rifles 7 WSM, Norma MRP & 7828SSC

Been out of the reloading/shooting game for a little bit and I'm finally getting back around to it and could use info on some load development/experiences.

Need to work up a load for my 7wsm Montana for the 162 Amax. I was running R22 and I think I tried Magnum too. But R22 was scarce the last time I made a purchase and wound up with MRP and 7828SSC. 7828SSC is awesome in my 243AI and I believe it would work well in the 7wsm.

However, after I thought about it, I think I'm going to try MRP first unless I can be persuaded otherwise. I have the MRP and I'm not currently shooting it in anything and needs to be used if it can perform.

Many thanks,
Nail

IMR7828ssc and Magpro gave me higher velocity than anything else I tried in my 7SAUM.

MRP is pretty much the same thing as RL22, so I'd probably drop back and try your old loads, working up to the same speeds as your old 22 loads.

7828SSC is pretty similar as well. Worked well with my 7mm WSM and 160 AB's.

That RL 22 shoots dead nuts accurate out of my 7WSM with 175 ole school Partitions. Have 3 lbs of MRP handy but don't use, read so often there the same, work up powder till you get your accuracies.
