Looks good, like the .720 better, did you have to have it custom made? or is that the predator choke? I'm using the .695 Puregold buckshot choke in my BPS with TSS. Take my chokes to Gun Docc and have him custom bore to size too, he did a PG .680 for my Benelli's.
That .720" is their Waterfowl tube. I do plan on having one made with the wad catching rings like their turkey chokes and see how that works.
This stuff is truely awsome and can't wait to shoot some more. Next turkey season looks promising with 3 hunts planned already so I'm sure I'll have some opportunities to test it on a turkeys head as well!
Sounds like you've run into the same problems that I and others have with TSS, finding chokes that aren't too tight. The XXX and tighter seems to be too tight, X and XX(.45-.55 under bore) seems to be the best range in the guns I've tested, depends on what your looking for in a pattern, but even if your going for high 10 counts, I start to get less in the 10 once I go past XX. If you know a good gun smith you can probably have him bore out a choke to a custom size, the other alternative is like you've done, use waterfowl, coyote, or buckshot chokes.
I'm seriously debating about boring my old Jellyhead open to .730" to see what it does? I'm a machinist and can do it myself vs. having a gunsmith do it.
I've got an IC .720 coming with the wad catching rings. I'm very curious to see if they make a difference or not. Depending on the results, I'll decide what I'll do next. I love trying different things and seeing what does what!
Hal is right though. After trying a .690", .710", and a 720" I've seen first hand that the TSS likes a more open choke. I'm sure that I'll be trying a .730" and .740" before next spring.
