I'm a big fan of 10mm as well. Got my first, a Colt Delta, in 1988. Sold it some time later, now have a Kimber. I like the Kimber better than the Colt, FWIW.

The cartridge is incredible, best package around. Handloading is a must. I like about any good 180 gr bullet, std primer, stout load of 2400.
