Un fortunately I believe that I have a Std. neck, ammo measured .253 loaded & remained .251 after firing , went in without a hitch, maybe with 6 ppc brass or another brand, But the Lapua will fit very nicely. Ill probably order 50 more I need a shim set for the wilson die anyway. I have some 223s that are shooting 50 gr. molied Varmint extremes into the 3s , I cant wait to try some of those as a varmint load. I used to shoot the Remington 50 gr. PLHP but their as high as any of the others now. They shoot EXTREMELY well & used to be CHEAP. NO MORE
