Thanks John! I just measured several Lapua factory loads and they go no more than 3.265", perfect for the magazines you mentioned.
Don't think you listed a COAL for your 9.3x62 loads in your "Medium Mediums" article. Do you keep yours to less than 3.3" or load them out a bit more given the longer magazine in your CZ?
Thanks again,
Rex
If I recall correctly the OAL possible in my CZ 550 is close to 3.35", maybe 3.4", because it's designed to handle standard .30-06-length rounds.
