I have a TC Encore I bought last year and have the one peice Talley Ring/Base set up on it. I have the medium on it. I have a Bushnell Banner 3-9x40 and it works well. By the way, hope you have enough eye relief with the scope you are using. I shoot 250 gr. Shockwaves with 150 gr. of Pyrodex pellets and it will get your attention if you are too close. I'm probably gona change scopes in the off season to a Nikon Omega due to it having 5" of Eye relief. Thank the Lord Oakley sunglasses are saftey rated. I shot this weekend and hunted. During my fine tuning season, it hit my glasses a couple of times.
