..... Are you guys using magnum primers in your RL22 loads??? I
I use Fed215's in the 270 with RL22.I started doing that after watching a friends 270 go from fair grouping to very good with RL22 and the magnum primer vs a standard large rifle.
I don't pretend to know exactly why but it worked in that rifle. I have used the Fed 215 with RL22 ever since and it seems to work well.
I started using RL22 back after MRP started to become scarce; or at least a PITA to acquire,and when RL22 was introduced.. Norma was not always the most reliable company when it came to delivering products over here.
Then Alliant brought out RL22 and some gun writers indicated the stuff was like MRP. I worked up 280 Remington loads with the new RL22 and the charges and velocities were similar to what Layne Simpson showed for the 280 with MRP.
I also used Rl22 in the 270,7 Rem Mag,300 Win Mag, 300 H&H,300 WSM,7mm Dakota etc etc. Always worked well.
I have no idea whether MRP and RL22 are same powder or not but some say it is.
Have not used MRP in a long time and ever since then saw no need since RL22 seemed to do the same things.
