True that these guns were fed whatever would fit in them.
There was little to no regard for chamber or cartridge length & pressure was not generally understood.
I remember this from my childhood, & also the cheap attitude of those who were poor farmers that lived through depression years.
They bought cheap guns & one box of ammo lasted them for years.
They could not afford practice shooting & my grand father used to chastise me as a bullet waster.
So, yes Raimey, I think most were not shot a lot early on & then ruined by the later high pressure ammo when the boys got a hold of Dads old gun, post WWII.
