I've got a Supernova on the way! I called choke-tubes.com and they told me that 3inch hevishot 2oz. #6's will out pattern a 3.5" with 2 1/4 #6's. They also said the 3inchers pattern more consisteltny over the ten shots they test their chokes with. They recommended I get a .650 choke. Anyone agree? Disagree?
