I don't have the 204 ruger but I have been shooting a Tact20 now for three years and they are tackdrivers...
The Tact20 is a .223 case necked down to 204 dia. and it has the sholder blown from 28* to 30 degree
The .204 is a 222 mag necked down to .204 with no changes
One thing that can be done to make the .204 a better more efficent round is to AI it and make it a 20 terminator
the 20's are flat shooters and inherantly accurate.... I have talked a few of my friends into them and they are happy they did it..
