10mm Ammo in .45 ACP Mags?

Finally, after years, I've found the best, most dependable 9rd. mag setup. Yes, it's the McCormick 10mm body with Wilson .38 Super follower and spring. Load it from the top down and wiggle the Wilson follower in and it works. Remember to break-in the spring by loading 9 rds. in the mag for several days.
 
I tried all 10mm and 10mm in the 45, except Metalform. And it's always the same, the tight 9th round that causes a jam. Put in eight and it's ok, but not nine.

Latest trick I'll try this weekend...a Wilson .38 Super spring and follower in a McCormick 10mm body. More on that later.
