Is this a new version of MRP? I'd like to know if it is slower burning or just an improved version. Any help appreciated.

It is a new powder, slower than MRP. My experience is that it is very close, maybe even similar, to reloader 25.

JohnS,

MRP-2 is slower burning than MRP. You'll find loads and information on Norma's web site.

Different sources would say that MRP-2 is the same powder as Reloader 25, MRP being the same as Reloader 22.

Identical if not the same as RL 25....Just like MRP is to RL22

Thanks everyone for the info. I think I recall hearing the Norma and Reloader numbers will pretty much the same thing but these days I'd rather ask and be sure!
