Come over to 10mmtalk.com or glocktalk.com and you'll find a wealth of information about high test 10mm loads.

As of 2004, IMR recommended 9.7 grains of 800-X under a 180 grain bullet. Out of a 5" barrel this hit 1320 fps and generated 34,200 psi. Remember SAAMI max in the 10mm is 37,000 psi. I have loaded this at 10 grains with no signs of pressure, but my 1911 does have a fully-supported barrel.

800-X is hard to work with because it meters so poorly, but when I am loading for deer hunting, it is what I use.
