I have been working up a good load for my model 10fcp .308.....It is the Dicks Sporting Goods rifle with the fluted 22" heavy barrel with 1/10 twist... I done a measurement to the lands with a sierra 150gr hpbt match, and a nosler 168gr hpbt match....I am getting repetitive measurements of 2.795 on both... Now the issue... The load data gives a col measurement of 2.800 which would jam me .005 in the lands... I have a howa .308 that measures 2.890 to the lands... Is this common to this barrel or do I have headspace issues?
