Here's a weight comparison of various pellet sizes, Lead versus TSS pellets, for those interested.
Notice that my #1B TSS pellets weigh about 1.2 times more than #00B Lead.
And my #0000B TSS pellets weigh ~2.5 times more than #00B Lead.
Combine that additional weight in a smaller TSS pellet diameter, and pellets that don't deform upon impact with bone or concrete, and it means big-time RETAINED DOWNRANGE VELOCITY, and PENETRATION.
If you can capture TSS pellets after firing them into a sand bank, they can be reloaded. Basically good as new. No pellet deformation.
I don't have access to pictures of the TSS buckshot loads I patterned on cardboard from my winter home/computer. Won't for another ~6 weeks. Just understand that TSS buckshot will shoot exceptional tight patterns, because the pellets are all perfectly round spheres, which don't deform. They remain perfect spheres, and therefore fly with much less dispersion than lead pellets. Lead pellets become deformed during shot column compression within the plastic shot cup, during quick acceleration down the barrel.
Because TSS buckshot doesn't deform upon impact, we've found the wound channels on body hits on big game don't cause as large a permanent wound channel, and flesh damage, as with soft lead buckshot pellets. Like shooting thru an animal with a non-expanding full metal jacket bullet with a rifle. Animals don't bleed internally as much as is experienced with lead buckshot. So I don't recommend body shots on large game with TSS buckshot.
Head shots should kill brain function. Instant death on charging bears, with a head shot.
