Hi all. I shot through my remaining hevi-13s last year so decided to give TSS a try. Apex 12ga 3" 2 oz #9 out of an 11-87.
Although I got very high 40 yd counts out of an Indian creek 665, I got a better pattern (less holes) out of an Indian Creek 673. Both chokes, predictably, were extremely tight at closer ranges. I could easily cut the 40 yard 10" count by 1/4-1/2 and still be able to reliably kill a turkey beyond 40, while allowing wiggle room at closer ranges given the extreme starting shot count with these number 9s.
For those of you have tinkered, what constriction/brand would you recommend? Off the shelf would be nice as the season here is about a month away.
