been researching the 460 and 500 S&W a lot lately and cant find much info. Many say just look at the 450 bushmaster but no real info on the calibers I am interested in. I am very curious on ballistics and trajectories for both out of 20" kathadin barrels and also custom 26" barrels. I am looking more at a 460 MGM barrel right now just because of the flatter trajectory but have also seen some custom loads for the 500 that are flat also. I am reloading so ammo cost is no difference just the barrel for my encore. Anyone with ANY info at all I would greatly appreciate it.
