Another weird thing I noticed. I know that you can't compare a wood board with a goose, but I noticed that shot of the same size gave the same penetration between lead and steel.
I'm sure it is related to the steel shot hardness but still I was expecting less penetration from steel due to their lighter weight.

Fabsroman, what kind of patterns do you get with the "T"shot and what kind of choke do you use.
"BBB"and/or "T" shot will probably be my next experiment in the "Undertaker"since it seems to favor bigger shot.
A good patterning heavy-duty combo is always handy to have around even if I should not need it too often.

About the static patterning thing, I know what you mean Skeet,
but a load that patterns good on paper is not always good in the field on moving targets. But a load that patterns poorly on paper, very rarely does good in the field.
Paper either for shotguns or rifles is always a good starting point even if does not tell the whole story.
