The Lapua brass is quite a bit thicker than the Hornady brass - Alliant used Hornady brass in their load data.
I haven’t measured Hornady brass case capacity but all the info on the interweb says...
That would be a good bet. What’s your max COAL in your .260 Rem?
I’d start with the Alliant website.
Alliant Powder - Reloader's Guide
Hornady don’t list RL-16 for the ELD-X in the book I’ve got.
