Shooting my .45's at 25 & 50 yards on a metallic silhouette range is what moved me to 10mm. Major, major difference in trajectory & knockdown. Not that you can't kill a deer with a .45, just that the velocity drops off very fast, and retained energy is low accordingly.
Stainless Delta Elite's were inexpensive then, and I wish I had bought more than one!
There are some local guys indicating that they shoot .40SW in 10mm's with good results. I've not thought through the actual implications of that, but they are indicating it works great and is a nice source of inexpensive plinking ammo. But I'd not try it without researching more. Extractor holds the round in place even as it's firing even though it's not headspaced on the mouth. Once fired, the pressure keeps it back against the slide face.
