Has anyone tried the 460 in a Encore Pistol and if so whats your take on it ?

Yes, I've tried it. What I would recommend is:
1. Make sure the barrel has a brake.
2. Shoot a 500 S&W Mag. for awhile; then the 460 won't seem so bad.
3. If you scope it, be sure not to skimp on scope or mounts.
I had a friend that for a short time had a 460 S&W Encore handgun barrel. Even with 454 Casull loads, the recoil was too much for him. I, of course, offer to let him shoot mine whenever the chance presents itself.
