Anyone have loaded neck od dimensions from lapua 6mm cr brass? Looking to get some bushings ordered. Rifle is saami chamber 277nk. From a little reading 269/270 is the bushing size used, but just wanted some hard numbers. Brass shipped out today.

Just if anyone cares or looks at this for future reference, the case walls average 0.0145, 0.273 loaded diameter. Using a 269 Horandy bushing to get sized neck od of 0.271 for 2k neck tension. The Horandy bushings must be bigger than advertised, as reddings will usually size to the dimensions on bushing or 0.001 larger with spring back. All my data was acquired using a FL bushing sizing rcbs matchmaster die with Amp aztec code 170 annealed brass.
