Thinking of going after a Gorilla? That's a lot of firepower! Is it actually a Ruger or the Taurus Tracker in caliber .480 Ruger? If a Ruger: SA or DA?
I own the Ruger .454 Casull (Super Redhawk) in 7.5". I like it very much. As such, I added the matching Ruger 480 in 7.5" as well. Both are D.A. The S&W .500 Magnum is D.A. too. The Magnum Research 45-70 in 10" barrel is my only big bore revolver in SA. These are all two-handed beasts. Anything .44 mag or less can be fired accurately with one hand. I hand load everything for these guys. It is much too expensive to use factory ammo.
