interesting reading, I've had my swaro z3 3-10x42 on my 7 3/4 lbs. 300 H&H for perhaps 5 years now, I suppose 350-400 rounds without issue yet, I guess any scope can go south. But I will admit once I got my 300 H&H load work done I've not fiddled with adjustments much.
Wondering if that 300 H&H's kinder and more gently recoil makes the difference. I absolutely hate shooting 300 win mags but no issues with a 300 wby 338 win.
