Following this. Seems like I read last year where Nitro had developed a TSS load for the guys who were using the old recommended choke for their Heavy Shot loads, which for the most part was the Rhino .660. I looked through their website last night and saw nothing about it. I as well as one of the guys I hunt with was interested in ordering some shells but the Rhino is not listed as a choke for their TSS loads?
