I have just received a custom 6BR with a .262 neck. This rifle is a rem 700,trued) action with a shilen 10 twist stainless barrel. The reason i had the .262 neck chambered is because i have a boat load of brass already turned for this neck size. One thing i didnt notice until today was the difference in the flash hole sizes. Let me back up here a minute. I have around 200 pieces of Lapua 6BR brass and around 500 pieces of remington 7BR brass that has been sized and turned. It is the rem brass that has a much larger flash hole compared to the Lapua. What i would like to know is how all this translates, or means to me? Do i need to reduce the powder charges for the larger holed rem brass? Do i use more powder? Will the larger flash hoe cause accuracy issues? Basically just trying to get some useful info before i start load work. Thanks Lee
