Pretty green to reloading, looking for some help from the Master Yoda's of reloading!! Trying to reload for a M-14 EBR clone with a Wolfe match standard barrel. I went through the process of measuring the chamber. What I came up with for my CBTO would be 2.133 in order to be 2 thou off the lands. Out of curiousity I measured a Federal SMK 175gr bullet and they had 2.223. The diference in OAL length seems significant to me, is the difference acceptable or do I need to reevaluate?
