I have been shooting the 210F for over a decade. It is very accurate and I trust it completely. When I first got it, I tried both
2 3/4 and 3 inch shells. They both grouped well but, I saw no reason to punish myself without seeing if the smaller shells did the job. I have never looked back.

From what I have read, the 3 inch 20 gauge will do the job. Why punish yourself with more recoil when the deer will be just as dead with the 3 inch shells. Once the bullets leaves the opposite side of the body, nothing more is being accomplished. The distances at which most people hunt with shotguns does not stretch the range of the 3 inch shells either.
