I don't know if I should ask here or start my own thread, but anyone have thoughts on regulating irons for 410s from my 416 and sighting a scope on QD Tally's in for 300s?

I haven't tried it yet but I'm betting that a Swarovski Z6 with 4.7 inches of eye relief and the long stock on the CZ550 will keep it out of my face.
