9MMand223only, thanks for your thoughts. Your #2 reason agrees with Shadow9mm's post above, the bullet being too long.
I can't find any post where I seated at 1.050, so I'm not sure where you got that idea. But it triggered my review of various manuals and it's interesting that the recommended COLs are all over the place.
Hornady's 4th Edition is the only one that lists the COL for their 115gr XTP as 1.050".
It is also 1.050" for their 124gr FMJ-FP. Lyman's 50th Ed lists 1.090" for the 115gr XTP and 1.060" for the 124gr XTP.
The Hodgdon No.27 manual lists Hodgdon, Alliant, IMR, and Winchester powders, and the respective COLs for 115gr bullets are 1.125, 1.120, 1.110, and -for Winchester - just 1.169MAX for 115gr, 124gr, and 147gr.
So the neophyte handloader with a 115gr bullet for 9mm is looking at any COL between 1.050 and 1.169.
