Thinking about the comments about shooting off the shoulder, that is a very good point. I ALWAYS keep the rifle on my shoulder as I cycle the bolt for follow-up shots and I just tried it with my CZ550 .416 Rigby and my BRNO 7x57, and the cocking-piece of both rifles gets very close to my eye. I have never noticed how close it gets before but now that I am looking for it, I can see that it is VERY close. I think I am going to have to try one on a lighter calibre and see how cycling, on the shoulder, goes with the aperture coming so close to the eye.
