So it's like this. I use any old .308 brass that's been given or I've bought cheap in the likes of Norma, FC, RG and Winchester and there's a big difference in the clean case weight and volume because of brass thickness between the manufacturers. For instance, Norma cases weigh 154gr while CBC weigh 186gr. Having said that and when I reload and test with well loaded cared for rounds I group sub inch no worries with any mix of cases.
Now I see some people being very fussy and in some cases almost superstitious about the name on the headstamp while others don't give it a second thought. What I want to know is factually speaking and short of competition shooting, why do some people swear by likes of lapua when in the real world the actual difference in performance from cases manufactured by lesser names is so small it can't be measured.?
