There is alot of hype with every new round brought on the market, and there are so many out there now that they mostly over lap in preformance now. I really can`t tell you how the .204 will do as I haven`t had enough time to try mine out, I`m still fire forming brass. I have 5 different rounds in .22 cal. centerfire rifles, and 3 different rounds in .17 cal. centerfire rifles and have been thinking of building a .19 or .20 cal. wildcat for afew years now, so when Ruger brought out the .204 it saved me alot of money getting into .20 cal. After I play with it a while I`ll make up my mind if I want to build up a .20 cal. bench gun, probibly a .20 BR. Sure the build-up is alot of hype, that`s to get the people that don`t by many gun to get one and means nothing to those of us that play around with alot of different rounds anyway because we already have a good idea of what we are looking for in our next gun.
Unless we run acrossed something cheap then we might end up with anything.
