Somewhere I got the idea to load 10 mm rounds with 40 mm brass. I almost got started on that I?m wondering what anyone has to say about it has anyone tried it. What is used for COL. how much Saturday to start with how dangerous is it like that I couldn?t find anything on the side about it.  Thanks Reed

I had been looking for a xdm Osp 5.25 for weeks.  Found one 4.5 last week EXPENSIVE but I like it.  Heavy.  Got me to thinking about the new kimber 9mm R7 mako which got me to thinking today about the xdm elite 10mm as a carry.  Went out to see one today at the local gun counter.  Now I?m thinking I need one ‼️   Plan to load down with a hard and heavy hitting super expanding goes in and not out boolit.  Got a recipe for me? Thanks
