I forgot to mention that I use DPX as well, but I switched over to HST because of cost. I cycle my carry ammo through each of my guns at least once every 2 months. That means I need to purchase a fresh box. In the case of DPX I need 2 boxes because they only come in boxes of 20. Since 20 rounds of DPX is roughly $30 and I can get 50 rounds of Federal HSt for $20, I can definately see the benefit of going with HST. Both are good rounds, but the HST does expand to a larger diameter. DPX would have better penetration by a slight margin. Especially if you're firing through a barrier of some kind.
