When I started around 1976, I could sign out a PD owned Victory model with 6 mismatched lead round nosed cartridges. It was so loose it rattled when shaken. It spit lead pretty badly.
We were supposed to be able to buy our own M66s through the PD. In the meanwhile, I carried my pristine M19 with hot 110 gr SuperVels. Life was good. They shot good for me.
I found a M66 brand new at the LGS and bought it. The first time I fired it, every one of the SuperVels primers flowed back around the firing pin, locking the hammer down until jiggled free. I found another load to carry after that. Our last revolver load was issued Silvertips.

Another thing I learned from matches... every round of duty ammo was chambered in the duty gun before carry... loaders too.
