Jbyrd this is what we always do, I don't know how many times I have to explain it

We use 12 gauge lead shot as the baseline to compare to because it is what everyone is shooting. It is how you can relate performance to people that have never shot tss, but still act like experts on the subject

We then compare a 410 shooting tss to the 12 gauge shooting lead shot

Of course a 12 gauge stuffed full of tss will have more pellets than the 410 shooting tss

But we are comparing to 12 gauge lead shot

Since everyone is so interested in my personal life........I get 3 weeks of vacation per year and spend every single day of that killing birds. We shot 10 cases of shells in 1 day this year hunting snow geese. Most Sunday afternoons I shoot a round of trap, which is 300 rounds per month or so allowing for one missed Sunday per month

Plenty for 25 feet away.

He said 10 yards. That's 30 feet.

Here's a 20 gauge load of #4 tss 1.5 oz at 1175 fps 40 yards. The circle is hard to see but it's 10" for reference. This is just the standard full choke in my sxp. I suspect it could do better with an aftermarket choke. I think you would be under an oz in a .410 load maxed out with a tps wad but at 83ish pellets an oz for #4 you could get into the 70 pellet range. #4 acts about like a good nickel plated bbb or #T shot so I would treat it like that when determining my effective range as far as pattern goes. You will run out of pattern with that kind of load well before you run out of energy.

Getting .410 ammo will be tough for a long time [ It fits in a handgun}

That is a good point. .410 is the only one I cannot find hulls for right now.

Ttt ADC j think there's something in here that might answer you questions

Thank you.

No data on factory fixed full chokes here wolfie but it'll give them guys that want to argue over their theories to rehash it,,, again!
