From 480 Ruger to 357 mag... that is quite a move. The 480 is a great cartridge. The Hornady runs about $30/20-ct box for the 325 gr XTPs. I have read that Hornady has discontinued doing the 400 gr XTPs. When they first came out, you could buy the same 325 gr boxes for about $18. It was probably the biggest bargain in a big bore revolver going.
You will feel even the modestly loaded Hornady's. But the recoil is controllable.
