.A good defensive ammo should have low flash, moderate recoil, penetration, superb accuracy and reliablity. DPX is all of those in addition to 100% weight retention. DPX is todays technology
choochboost said:Its not that the XPB does not expand reliably, if it didn't it never would have made Dr. Roberts list, the expanded diameter is just not as much as some others such as HST and Ranger-T, especially the enhanced version.
YukonGlocker said:I tested the Corbon DPX 9mm. It expanded fine; but it penetrated less than any other hollow points I've tested, especially out of short barrels.
