TSS is legit. I believe it's approximately 54% more dense than lead. Seems like I read that a #9 tss is equivalent to a #5 lead in regards to density. Which allows you to load way more numbers in a wad without compromising energy. I have been hand loading tss for the last couple years for turkey and just finished up my first year of waterfowl hunting with TSS handloads. It is I bit pricey but I enjoy hand loading and have no plans of going back.
I shoot 20 guage and .410. I killed 10 big Canada geese this year with a 20 guage, 7/8 oz. #9 tss with IC and Modified chokes. On a solid hit geese will fold dead like a towel. I just got into waterfowl loads so I don't have any pattern pics or numbers data yet.
I will post some pattern pics of some turkey loads from 20 ga and .410. Last spring my then 9 year old son killed a tom I ranged @39 yards stone dead in Nebraska with a .410 using tss #10 handloads. I killed a tom in Texas ranged @51 yards with a 20 guage 1 5/8 oz #9 tss.
The pics will be pellets counted in a 10" circle at different distances.
.410 114 #10 tss in a 10" circle @50 yards with turkey full choke.
.410 193 #10 tss in a 10" circle @40 yards turkey full choke
20 guage 326 #9 tss in a 10" circle @40 yards .575 choke
20 guage 85 #9 tss in a 10" circle @60 yards .575 choke.
Don't have any 50 yard info for 20 guage.
