Hello! I read some similiar ballistic info at ammolab and really believe this gun is a lawsuit waiting to happen if in fact the ammo is loaded to the levels published online.
I wonder if the buyer will have to sign a legal disclaimer, having seen my share of Casull forehead dings and even firing a custom Linebaugh .500 Long ONCE, somebody will break their wrist.
I have some years of experience with the Casull but the regular Linebaugh loads of 440s@1500fps are painful.
PS, ammolab mentioned the velocities were reached with a T/C fourteen inch barrel so who knows?
