Nope, the two are not the same thing, not even close UNLESS you are talking about the same, exact bullet.

Same weight bullets can be VERY different in length.

These two bullets are the same weight and have the same "type" of nose. With the same OAL, which is going to have the deeper seating depth?




Okay, say you build your load with the shorter bullet, the one that gives you less in the case and your load is a "real" maximum (not one from a book). Say you seat to the same OAL but use the longer bullet AND your thought process is "Aren't they the same".

You are flirting with a problem friend and someone that is loading ammunition, needs to understand the difference.

FWIW
