... How do you get a fuller, denser pattern? You choke it down.
Or add more shot to the payload. And that's why you are using 9's and not 6's in your .410.
Forgot about this. 😆 How exactly is it you think switching to a different shot makes the pattern of the original shot change? These things do not relate. They're completely different loads. You can't load T9.5s and get lead sixes.
If you want to understand this stuff you really have to let go of the winning an argument nonsense. Try to learn instead.
Lead isn't even in the picture for the .410 past thirty yards. You have to go to to TSS if you want a forty yard pattern. Even then you have to choke it down. Adding more pellets is not an option because you have all you're gonna get already with small TSS and available shot cups.
