Clark,

First, double check your target from the factory, it should be 50 meters, mine was. Next shoot it of the bench. Get a 25 pound bag of shot, empty it (save the lead), refill with sand, put between shoulder and butt. This is how I work up a load. I can shoot my double like a varmit rifle when I don't have to think about recoil. I shoot 6 rounds (right-left, rest, right-left, rest, right-left) I keep playing with the load (powder and loads) untill all six are clustering around the 10 ring in a sub 3" group. It is very tedious as some load are terrible. It took me 10 trys to get the 235s to regulate, the 270s shoot out the 10 ring on the first load. I'm still playing with the 300s. I think I would go for a 500 over the 470 because of the bullet selection. Hell, you could even try .50 cal. sabots!
