<font color="blue">For the record
Back in the day, when Mark IV scopes were REAL Mark IV Scopes, and were very expensive – 10-years ago - I owned a VXIII 4.5x14 40mm which I sent to Leupold to have Target Knobs and a 'black ring' installed, and thereafter sent to Premier Reticles (at Leupold's suggestion) to have a Mildot reticle installed.
This was a 1" tube scope, and I mounted it on a 300WM using the Mark IV bases and rings (yup, they made 1" rings).
Of course, this was prior to Leupold getting the geometry right on the Mark IV rings – on the 'old' Mark IV rings the upper half of the scope rings would crush the scope tubes.
My rifle would shoot consistent 1/2" groups, all day long, with the scope tube crushed by the rings.
The fact that Leupold's rings crushed Leupold's scope irritated the snot outta me, even though the rifle shot incredible, so after talking to the folks at Leupold, and at their suggestion, I removed the scope from the rifle and sent it to them to have the tube repaired.
The scope came back with a new tube, and I had a machinist fix the Mark IV rings – actually manufactured 2 new caps for the rings – and I reinstalled the scope without crushing the tube.
Only prob was, using the exact same ammunition as before I sent the scope in, the rifle would now print 2 distinct group, consistently – same 2 groups, same distance apart, and same orientation to each other.
Of course this irritated the snot outta me so I called Leupold and they said 'send it back', which I did, and they then sent it back to be and said "nothing is wrong with your scope". I reinstalled it and it was shooting 2 distinct groups… Sent it back AGAIN. Got it back from Leupold and installed it AGAIN, and it shot 2 distinct groups… AGAIN.
Sold the scope – the person that purchased the scope called me to discuss the 2 DISTINCT GROUPS his rifle would shoot with that scope…
I could write a second synopsis on 2 other people that owned Leupold scopes that would print 2 distinct groups… but I am tired of typing.
I can not put a Leupold scope on a rifle because I no longer have FAITH in the scopes – no matter HOW MANY TIMES you send it to them for free repairs.
Lastly, I know someone that, in fact, got an invitation to visit the Leupold Facilities... his observation was "their repair facility is twice as large as their manufacturing facility".
