Last time I worked up a load for my Wby .300, I couldn't find MRP in Stock anywhere so I went with RL22. Now it's back on the shelf at a few suppliers. That load gave pretty good results but now I'm low on powder and need to restock.
Curious if anyone has worked with newer lots of each of these to see if they still perform close enough that the charge may be similar. Seems RL22 has always had the reputation of inconsistency from lot to lot where MRP was a more consistent powder. That's why I originally preferred it over RL22. So what's the skinny on these currently?
