carry a 642 j frame. per my reading on here and from the FBI reports,carrying fed 148gr match WC. win/fed,other would be ok,just have fed on hand. planning extra ammo to be lead semi wad cutters (ease of reload). any data on the performance of either 148gr match vs 158gr semi wads? brand recommendations from existing data. magtech,win,likely others have that ammo. buf bore hard cast likely ideal but $ matter when putting back a supply. thanks for any input.
