I shoot a 470 Heym,first up you should be using a chronograph,I have hardly ever shot factory ammo in my gun,I did shoot some ammo,federal that was given to me by my smith & it was too hot for my liking,my safety jumped halfway,
You need to get the velocity upto what a 470 is designed for 2150 fps,your rifle will regulate close to that velocity,you do not need two shots in one hole,2" @50 is excellent,I use R 15 in my gun with foam filler.
