I am loading up my first ammo for my FCP-I .223, and have a question regarding max cartridge OAL. I am loading Nosler 55gr and according to Nosler's Web site, the max OAL is 2.260". I can load a dummy round to 2.365" and it will fit in the magazine and not contact the rifling. I hear about loading to just of the lands and understand the process, but my question is, is that for longer bullets (ie, 69gr+), or can you do this with these 55gr bullets as well. If so, then what is the guideline for the minimum about of bullet that must be seated into the case?
