I have never used bullets that weigh less than 158 grains in my N frame .357 magnum revolver , I have heard that .357 loads with bullets that weigh 125 or 110 grain can cause noticeable flame cutting on the top strap of revolver ! I've been thinking of getting a small J frame S&W .357 revolver ( all stainless ) and figured I'd try 38 Special +P 125 grain loads in it but not full .357 magnum loads with lighter bullet weights ! Question is do 38 Special +P 125 grain loads still show noticeable flame cutting damage as its big brother or is it mild enough to use extensively ? Thanks !
