I saw someone on YouTube shooting .32 ACP ammo in a .327 magnum revolver without any problems except for one dead round. He didn't get into how accurate the round was. I have a Ruger GP 100, .327 magnum which I've never fired. The recommended ammo for it is expensive. That would be .32 S&W, .32 H&R magnum and of course; .327 magnum. The .32 ACP is much cheaper to shoot and I would therefore prefer to shoot the cheaper ammo. I would appreciate any input from someone with any experience or expertise in this area.
