I guess I should have said that whenever I get into a new caliber, I have this need to reload for it because I believe I can get my best performance from that rifle if I do. I think we can all agree that factory ammo has gotten much better through the years and in some cases is very hard to beat with reloads. The best 3 shot group I have ever had was with factory Federal 70 gr ballistic tips in my .243.
My point with the .223 "and" the .204 is I am not yet convinced there is such a difference between the two that it justifies more dies, bullets, powders, brass, etc. I usually spend around $100 to get started in a new caliber for these items and the .204 would even be higher because of the cost of new brass. There is no doubt that the .204 is a great performer as Mitchell and others have witnessed through their experiences.
There is a .204 Handi still sitting in my gunshop with a bull barrel. It has been there now for over three weeks for $210. Hmmm... I have some very accurate rifles in .223, .243, and .300 wsm that I am really pleased with. Maybe, I should get a medium bore like a 7mm-08 or a BC.
