Norma MRP = Re22 = Win WXR & roughly equal to W780. Re19 is just a bit faster and Re25 is a bit slower. MRP is one of the BEST high-energy slow burning powders on the market - maybe the best. | |||

Norma 204 = Re19 Norma MRP-2 = Re25 Both subject to the usual lot to lot variations in both lines. | |||

1st H-4831 2nd norma-MRP 3rd RL-22 4th Win.-785 RL-19 is closer to N-160 norma 204 | |||

The Norma line of rifle powders and most of the Alliant line of rifle powders are made in Sweden by Bofors. Norma MRP is the same spec powder as RL-22, not RL-19 which is the same spec as N204. These lines of powders are infamous for greater than average lot-to-lot burning rate variations. You can interchange MRP and RL-22 in essentially the same way you can interchange two different lots of either, ie., by backing off and working back to your original load watching pressure indications and velocity. | |||

I heard that the MRP and MRP-2 have less variation than Reloder powders? Are they in fact the exact same? What a let down. Love shooting precision and long range. Big bores too! Recent college grad, started a company called MK Machining where I'm developing a bullpup rifle chassis system.  | |||

I know the Weatherby factory 338-378 loads that I shoot are very, very close from lot to lot and don't seem to be very temperature sensitive. That ammo is made by Norma. I haven't tried any of it for my hand loads as I get very good results with IMR 7828. The IMR is fairly temperature sensitive however. Ken....

I think I will try MRP-2 in my next 6mm Ackley barrel and 338 Lapua whenever it's done. Love shooting precision and long range. Big bores too! Recent college grad, started a company called MK Machining where I'm developing a bullpup rifle chassis system. | |||

Not quite the same, but pretty close to RL22, which is not a bad thing, RL22 is my favorite magnum powder from 270 to 300 Win to 338 win to 340 Wby, I've gotten good accuracy, high velocity, and no pressure signs. Jl | |||

I have both Norma MRP and Reloader 22. I have 5 one pound cans of MRP with 3 different lot numbers. These all load grain for grain with each other. I also have two one pounders of R-22 with different lot numbers. Both of these shoot grain for grain with each other, but not with the MRP. My lots of MRP out perform my R-22 in both velocity, accuracy. R-22 just can't keep up to MRP in the velocity and accuracy dept. If indeed they are the same powder, I don't see it. | |||

Well I certainly am going to try MRP-2 now! Love shooting precision and long range. Big bores too! Recent college grad, started a company called MK Machining where I'm developing a bullpup rifle chassis system. | |||

The lots of MRP that don't meet spec must go in the R-22 barrel  "Experience" is the only class you take where the exam comes before the lesson. | |||
