I agree 200 yds is a long way with a air rifle, but my Crown will shoot one hole groups at fifty all day, I like the challenge of the distance to keep it interesting. I think the 700mm is the way I will go. I appreciate all the input.
I am looking to order a M3 soon. My question is, what is the difference in performance between the 600mm and the 700mm bbl. I won't be shooting much farther then 200 yds. Will the 600mm be fine for that?
