I have a Diamondback HP on a Howa .270. Took less than a box of shells to sight in. First shot hunting with it is a miss on an antelope buck under 200 yards. Get it home and I notice the thing is rattling. Vortex warranty will cover repairing it, but in the meantime I have to mount another scope and get it sighted in dead nuts in the middle of hunting season. Went back to my old Redfield scope and ended up filling my buck tag with that.
Read somewhere (after buying that Vortex) that it probably isn't good that so many people know how great their VIP warranty is. Really a good point that I never thought of. Less than a box of shells of .270Win and one of the lens came loose inside the scope? Pretty sad.
I'd be hard-pressed to buy/trust another Vortex scope.
Interesting story. I wonder what happened. I have bounced my Diamondback off of rocks, transported it thousands of miles in the truck and packed it for probably close to a 100 miles on a pack without any problems. Matter or fact, there have been a handful of times that I have been sure that I damaged it, but it has still held zero. I have beat the crap out of mine and it has been great. Sorry to hear about your experience.
