I’m sure it’s a photoshop, but you are one guy who would look at it and go....”hmmmmmm”.....
Bingo. But I am a bit more discerning. That 500 S&W Mag and 460 S&W Mag are enough in the revolver world. I went to a T/C Encore frame to fire rifle cartridges from a single shot pistol format. My wife shot the .308 pistol with a 170 gr bullet on top. She almost chipped a tooth when it produced a lot more recoil than she anticipated. We now load .308 and .30-06 brass with 100 gr Speer "Plinker" bullets. That reduces the recoil to a manageable level in the pistol format. I would still like a 5.7x28 T/C rifle barrel. The blow back action of the FiveSeven pistol leaves the case neck with a slight balloon. Not good for reloading. I think a single shot chamber would support the brass properly and make it easier to reload.
