Could regular rifle barrels be repurposed for a PCP rifle. I’m talking 6mm\.243, 30 cal, even .270 maybe? If someone was fortunate to have a few higher end take off rifle barrels. These were taken off new rifles that the owners wanted to customize them with higher quality barrels. Some are already in oddball calibers like 300WSM and 270 WSM that can’t really have their chamber recut to a different caliber due to the thin barrel taper near the chamber. Can the chamber be cut off, taper cleaned up and reused? I understand that the barrel twist might not be ideal with lighter air rifles slugs. And I know that there might not be a market for a .270( .277) slug. I just want to use what I have on hand in my shop. Some geographical locations are limited for supplies.
Duane38, I have some blanks in the same .357 1-20 twist so I possibly start with one of those. Is this slug an off the shelf purchase? Could I possibly buy a mold to cast my own? NonGrata, air rifle pellets or slugs need to be able to easily be pushed through a rifled bore with little resistance? The only thing I have had to push through a barrel lately is a bronze brush. Would it go through with light resistance like a tight cleaning patch? I once had a squib 9mm round get stuck in a Browning Hi Power barrel. It was a bear to remove with a hammer and brass rod. And I only had to move it 4 inches
I've used .30 cal and 9mm PB barrels, but I lapped out most of the rifling (a long and tedious job) because the grooves are to deep compared to air rifle barrels.
