Yes sir I have two. The jacketed bullet only muzzle brake and the cast bullet use muzzle brake. I use only the cast bullet muzzle brake because it seals the top ports and extends the port out in front of the front sight. Effectively making the 460V a truer five inch barrel and jacketed bullets shoot fine from it. My 460V was worked over by Cylinder and Slide including bead blasting the finish. And TK Custom altered the front of the cylinder to accept their stainless steel moon clips in 45 ACP. Using Starline brass the 460 Rowland, 45 Super and 45 Winchester magnum cartridges all fit the 45 ACP moon clip. I also had installed a Cylinder and Slide extra long firing pin so rimmed cartridges do not need a moon clip spacer for reliability.
