I used to own a .223 which I ended up swopping for it for a .243. I loved the .223 but didn't have to use for it as I was mainly using it for roe which was good if you hit them right, less good if you didn't. Hence the variation.
The reason I am asking about the .204 is due to the dramatic quality reduction in the ammo of my .17 hmr and the groups widening to greater than a rabbits head which is worrying. I have heard it can be a good replacement and if home loaded which I will do it can be a very accurate round. What are people's experience of this calibre?
