Thanks Groo. I had read about converting 10mm revolvers to 10mm Magnum many years ago when S&W first introduced the 610. But, as with many ideas, I did not pursue it. Now with the Rugers available it again looks tempting. I'm not clear on why you think case tension would be a problem. One of the reasons for the 10mm Magnum case is you can load longer, have more powder space and not have to long load standard 10mm cases which reduces case tension. I am thinking about 230 to 240 gr cast bullets with a .300" meplat, loaded to about 1050 FPS. Should have deep penetration and blow right through average size feral pigs. The bullet design I was looking at has about a .400" long nose in front of the crimp groove so I will have to do some calculating to see if it will work in the Ruger with 10mm Magnum cases. This will be a step up from 357 Mag and yet smaller and lighter than an S&W N frame. I have some of those and like them, but in my old age I'm about smaller, lighter and handier sidearms.
