Anyone have a source? No luck with local dealers or on-line sources I have looked at.
Thanks and stay well,

Paul, the last time I spoke to Grafs they were discontinuing carrying Norma powders. I'm told however (unsubstantiated by me), that RL-22 is identical to MRP.

There is a very fine line between idiotic and clever. Most internet posters have no idea where it is.

Yes,
Graf said they are dropping Norma powders. Others have said that the two are identical, but since the burn rate tables list them seperately and quickload has different pressures generated by the powders while keeping everything else equal, i ahve my suspicions that there may be a bit (if ever so slight) difference.
Thaks and stay well,
Paul

Yes, they're both made by Bofors in Sweden. RL-25 = MRP2, also. And there are others.



Of course, normal load development should be utilized when going between the two powders (i.e. start 10% low and work up).

Hi RSY,

You are right, or course. I think we should always back off when using a new can of powder, even if the same type but from a new lot#.
Thank you and stay well,
Paul
