Just purchased a Winchester mod 70 223 WSSM Feather weight Synthetic. I was not pleased with factory ammo in the factory rifle. After glass bedding and trigger job i have had some better accuracy sucess but think it can be better. Does any one know any load data for this cal. besides the typical stuff published everywhere. My real question is does anyone have any advice for 1.bullet gr weight,
2. Powder suggestions
3. Load charges
4.Primers?
Notice: I have also read of some problems loading over 4200 fps. in that the low density of the 22 caliber jackets actually disintegrates after exiting the mussel because of extreme RPM supposily over 300,000 rpm.
Any help would be appreciated WAC
