[QUOTE="Chuck32571, post: 1439134, member: 94321"] I use 24.5 grains of IMR4895 w/Sierra 69 grain bullets. No matter how careful you are, the short neck of the 223 will cause Concentricity problems with your finished product. I use the Hornady Concentricity gauge tool and correct it within the .003 they recommend. Most of the time I get it within .001 which produces 1/2 MOA groups or better all day long. Would also recommend you check your cartridge lengths to sit within .001 of the leads with your bolt action to prevent excess jump which kills accuracy. [/QUOTE]
