With this 1 pin I can effectively kill a deer from point blank to around 40 yards without having to compensate much. I feel comfortable with that.
But you see, you've already induced a margin of error that to manyof us is unacceptable. In the range you're talking about I really doubt that you're within the kill zone. you're inducing fringe hits on a paper target. Add a real live animal and you've created a miss or a bad hit. Someone mentioned the old pie plate. Maybe if you're shooting a recurve and don't practice a lot. LOL Really, the old pie plate puts a lot of arrows where they shouldn't be.
As far as my margin of error. I pick and choose and do whateve I have to to get broadheads to shoot with my field points. So my margin of error is not different. A 3 inch margin of error gives you a 6 inch circle. That's getting mighty big and in my opinion, unacceptable when shooting paper. On an actual hunt I hope for far less. I aim for "The Spot" and when I miss it..... it's unacceptable. I'll take all the lucky breaks I can get, but I still don't like to miss what I aim at. That's one reason I could never be a one pin kind of guy. Before I'd do that I'd throw away all the sights and shoot instinctively.
