First, ignore the OAL in the manuals. Now, determine what OAL is required for this loaded bullet to fit in your barrel(s). Use a magic marker and follow the method in the link below to determine what OAL will fit in your barrel until the round will free fit and rotate in your chamber. https://www.shootingtimes.com/editorial/reloading-tips-the-plunk-test/99389 Then tell us what that OAL is. P.S. That bullet has a very short nose so it looks like it will require a short OAL. There's nothing wrong with this bullet. It's just a different shape than what you've loaded before. P.P.S. You need to do this for EVERY new bullet you load with. Really.
