127 yards, 41 mag with barnes 180 xpb. this is MAXo thisgun You might be able to stretch the 460, 500 or a 454 to the 150+ range. I never take a revolver to an area where i expect to shoot beyond 100 though. The energy and ability to penetrate with revolvers out at 150 and beyond really drops. To me the revolver is just like my bow......It is a closer range weapon. It is great sport to stalk to the 100 yard mark(or closer) to take game with a wheel gun. Besides, if you need to shoot further, grab a tc or an xp.....400+ is not that uncommon with the right long range set up/
