Maybe a stupid question, and I assume the answer is probably no. I'm curious, would jacketed slugs meant for PBs work well in our PCP airguns? Is it even safe to the barrel or could the harder jacket damage the rifling?
My guess is that they wouldn't conform to the rifling as well as a soft lead pellet and you'd risk getting one jammed in the barrel. It takes a ton of pressure in a PB to push a copper jacketed bullet.
