I am about to buy a new bolt head for my 223 Rem Axis. I understand from reading previous posts that all Axis replacement bolt heads should be of the short action type. However, Midway, which seems to me to be the best source, has both 'large' and 'small' firing pin hole versions on offer. Which one do I want?
