The 204 is a great round. It is extremely accurate and fast. There are a lot of options if you reload your own. there are others tat are really good like the 20 Vartag, but ammo and brass is even harder to find.
Made a sweet deal yesterday on a new Savage Model 11 in 204 Ruger at a Cabela's in Omaha, Ne. I took a New Model Ruger Blackhawk in .357 Magnum and traded it in for the rifle along with a little over $90.00. I got more for the revolver than I paid for it! I made up some rounds using the small rifle magnum primers and will take them out to shoot later today.
