Work up your rifle may be different.

This is the data from my notes, I had tried 2209 and 2213sc with all the projectiles and these were the best groups I could get. From memory these could have been fine tuned but I was just after a hunting round for the rifle quick. I didn't have the rifle long so the load development did not progress.
