Well the main culprit in the .357 mag was the hot 125gr JHP ammo, but like I posted mostly the S&W K frames had most of this issue, my 686 didn’t nor did my model 28, now todays guns I don’t believe have to much of this issue, and like @HansGruber posted the light weight scadium revolvers have that blast shield to prevent it from happening.honestly guys, i was not aware of the many other types of ammo. it is interesting to me now, as to why all the different types that were developed and still in use today, albeit, i'd imagine a higher price to obtain?
i wonder the thought process of the people that developed these other types of ammo, and the reasoning as to why, over say what was/is already out there.
interesting educational channel, the site has going on here.
