Thread: no lead from 2021

3" 20 guage is a bit of a hard case...sort of like the 3.5" roman candles in the .12ga
you push a big payload out of small bore and its going to hurt,either of those shells with smaller payload wont boot the same.
push a 1oz load out of either and it will be mild...up the .20ga to 1 1/4 and you starting to ask a falcon to fit into a minis parking space,the payload will be longer and harder to get moving as it has to squeeze its way through.
push a 3/4 oz load at 1300fps out of ANY of the guages with same weight shotgun and felt recoil SHOULD be similar the pattern board would be interesting.
trouble is and always has been when you get lightweight gun and feed it heavy loads.
