I do have a set of globe sights on a H&R Buffalo Classic, and while they work great at the range, I'm not sure how well they would work in the field on game. The double ring would seem to cover up too much of your target for optimum aim. Not a problem with paper, but it would quite different on a deer. You might have to try different inserts to find the one that works best for your conditions. My rifle came with several inserts and I haven't really messed with them too much. I do have one that is simply a yellow lens with a hole in the middle which might work well on game. Another option would be a cross hair type insert up front.
