I have been using LC 308 military brass in bolt guns since I started reloading. I also use lapua and Norma brass. One needs to reduce the powder charge by 1-1.5 grain due to the reduced internal volume (thicker wall) of the LC brass. Also need to swag the prime pocket the first time it’s prepped (to remove crimp). No difference in accuracy. Prime pocket stayed tight after 10 reloading ( I never went beyond that). The speed may be 50 fps slower than lapua brass due to smaller internal volume and reduced charge.
