I'm on my 2nd barrel made for the 223 Valkyrie I neck sized up to 6mm. This is a one pass with the full length bushing die. With my 22" Krieger I'm getting 3180fps with the Hornady 75grn vmaxes. This is using 27.4 grns of H322.
My 2nd barrel I just had made is a 16.5" Krieger with a .750 diameter barrel. With this one my preliminary loads are chronoed at 3080fps with 65grn vmaxes. This particular load is using 27 grns of H322.
