Like steel the pellets are very hard and could damage the choke as they are squeezed through. Can cause ring bulge in front of the choke. I googled this info. thanks All SXS OHIO

I googled mine also and supplied the verification from Federal. Who I think most would consider a valid resource..In addition we are talking small shot which passes thru the choke much smoother....

Anyway, given a chance I will give Federal and Apex a call tomorrow and ask them specifically about TSS and older shotguns...

Hang on....

As for drop my turkey guns that I use TSS in have red dot sights which I zero center of pattern at 40yds so drop for 40 to 60 yds is insignificant . I consider 60yds max range with #9 TSS.

Google....

heres a warning on a box of 20 ga turkey shells tungsten load....caution\...heavyweight tss shot may cause barrel damage to some guns...our special protective shot cup is designed to prevent or minimize this tendency but we do not accept responsibility for such barrel damage resulting from the use of these shells....I have shot tungsten shot trru some of my full choke guns with no damage thus far....patterns good out to 60 steps for me but at 70 steps its not a good pattern for me...all my shots thru fixed full choke guns....charlie

Thank you....

Just noticed this on an APEX TSS box...

"Apex Ammunition recommends choke constrictions no smaller than 660 for 12 Gauge loads and 555 for 20 Gauge loads."

Which is getting into tight choke constriction.

Combined with the slower speeds, lower pressure and the wad they use, if I decide to use them, I'm not going to worry about it too much....

However, admittedly there are options out there that have worked well for years....The TSS advantage is with smaller shot, it raises what can be done with the smaller gauges....

.660 for 12 gauge choke? That's about a .067 constriction. I've never seen anything much tighter than my .044/044 Sterly

There are Turkey screw chokes that are advertised to 660. Carlson makes one..

Question: Black Dog pic on your profile page, English Cocker? The one with the Pheasant.

You can get them tighter than that also depending on the company . I used to have a .650 for my 12 gauge pump . I have also used in the 10 ga a .7000 and a Trulock .680
