COL= either Cartridge Overall Length, or Case Overall Length. OAL could be anything. The problem is lazy people not wanting to take the time to spell things out. In your problem you're concerned about cartridge overall length.
Since you neglected to give what powder/primer you're loading, we can't give you any advice. That's where COL comes into play, the loads Horandy worked up were for that shorter COL. IF you used the powder they used at that COL, you're safe. IF you used data from some other source at that shorter COL, then you're not safe.
