Cabelas has the Pedersoli...
...but it seems to me to be little more than a novelty.
I guess if the criteria is big and bad and in your face (or a tiger's face ), I'd have to go with the S&W 500...or a similarily chambered BFR. Notice how I give a nod to the SA enthusiasts among us, rather than just touting a S&W product like I'm sure many of you expected.
Since I have no plans on a trip to India...I get enough of that accent from all the solicitation calls I receive at work ...and I'm not about to strap a howdah on top of my Silverado...I'll stick with my .44 Mags.
