If one considers who developed it and his audience / student being Long range hunting and shooting, it's applicable. I've been consider a March 4-28 as an all around scope and my Tract 4-20 is really all the scope I need. but then so is my Tract 3-15. At the sniper school I attended 20 years ago I used a Leupold MK4 4.5-14x40 1 inch tube and most of our shooting was done at 10 power or less and the USMC snipers used straight Unertl 10 power scopes for a long time. Times change, as does every market and perception of what equipment is necessary to accomplish a particular task. James has designed a very capable scope that meets the needs of his market, or audience if you prefer which is reasonably priced for what it is. If one doesn't think that it's necessary or practical, fine, buy something that suits you but please be considerate of those who appreciate the work and thought that went into this project and did see that James is working on a 3-15 version?
I try to always respect that we all have our own opinions about everything and I never take ownership of other people's stuff. (thoughts, feelings, issues etc.)
