WTB: 577 barrel blanks

Hello

Looking for 577 blanks 1:18 or 20 twist contoured or straight.

Thanks

Re: WTB: 577 barrel blanks

McGowan sells 577 barrel blanks for about $235. They recently purchased new tooling for the caliber. They list a 1:24 twist but I bet they would rifle some blanks at a faster twist for you. However, a 1:24 twist will sufficiently stabilize the longest copper bullet on the market at 1500 feet per second.
