I imagine it would be quite a handicap as the depth of field will be short and the possible px error at the extremes with shooting fixed px with an objective that big is going to make it tough!
You would be better of with a much smaller scope, anything with a decent mag and multi aimpoint ret would be ok to have a dabble at HFT. If you get hooked buy something that really lends itself to the discipline.
Have you got a cheap 3-9x40 mildot knocking about? I have a few if you want one.
HFT, for people with only 2 buttucks!
