"T" shot is .20 "diameter, if its lead. I thjink the steel shot and the lead shot are the same size. As lead, there are 36 to the ounce, so steel ought to be about 43 to the ounce. I suspect they are used for long range geese.

How you get an effective pattern out of 63-68 pellets is beyond me.

T is 2 sizes bigger than BB shot ( 0.18" dia) and one size bigger than BBB ( 0.19").
