Recently bought a vintage Ruger Blackhawk made in 1967. This was before the new model came about so it has the three screws, etc. But, the previous owner did install a transfer bar.
Anyway, it is chambered in .357 and works wonderfully with said cartridge. However, when firing .38 specials, I ran some Winchester whitebox and magtec rounds through it in 38 and only about half fired. Each had a dimple in the primer, but did not go off. Then I loaded it with six Federal hydroshock .38's and all of them fired.
From what I have stated can any of you tell if this is likely an ammo issue or can the striking of the hammer an adjustable thing on the Blackhawk?
thanks,
