Might have to open the choke up some with the TSS. Rob Roberts Custom Gun Works recommends their .675 in their Final Strut choke for TSS loads. I just got a Rob Roberts choke and am loving it. That said I’ve always shot Sumtoy and Indian Creek. I’d pick what choke you want to try then email them and ask what constriction they recommend for the gun and load you’re shooting. They know how their chokes pattern and that’ll keep a lot of the guesswork out of it for you.
