Powders Used / TSS

[Greg Massey]

Do most of the powders that are used with TSS shells leave more of a powder residue on the gas piston rings in Auto loading shotguns?

Same with the barrel getting dirty also with these shells?

What have you guys noticed using these TSS shells?

I could be wrong but I believe my handloads are slightly dirtier then others. I chalked it up to the slower burning powder.

I don't think so on Factory Loads .
Those powders in turkey loads burn fast to match the trend towards short barrels for turkey hunting.

Handloads if using slower burning powder I could see it.
