Well said Jim
I am the tipical middle of the pack shooter and certainly not my friends Larry Costa, Mike Ratigan, Gene Bukys (he uses his own frozen scopes/system),Bart Sauter and many others (I wish I could do what they regularly achieve but I keep trying...). After using in competition for about 15 years a very well known scope brand that I had to return (excellent service though) every year for inspection/repair, some a few times/year, when March showed up in benchrest I changed to them and have since several scopes and would not change them for any other brand, and yes I tried the most known ones.
Why do I use March scopes? Simply because I have yet to detect a "suspect" POI change after all these years and many, many thousands of shots and to me this is a good reason to keep using March. I have no particular reason nor interest promoting March just making "justice" to a good piece of optical equipment, expensive? Yes but you pay what you get!
