One of my favorite 2-7/8" 10 gauge loads is 3-1/4 drams (90 grains) FFg with 1-1/4 oz of shot and whatever fiber wads fill the case for a decent crimp, preferably rolled 'cause they look right.

Nice and smokey, too. Usually Federal plastic hulls take 2-3 firings with this load before they melt through.
