There are many different bullet shapes, and the shape often decides what OAL is proper. The 1.135” is usually meant for a button nose wadcutter, which is why the RN bullet looks so odd at that OAL.
Since these are RN bullets, they will typically be loaded 1.200” to 1.275”. Berry’s shows on their website a recommended/suggested OAL of 1.250” for this bullet. But you need to confirm its proper OAL with the Plunk Test.

Then select a caliber from the drop-down menu.
Lee does not tell you which exact bullet their data is for, so it’s not the best resource.
