100% weight retention, 2X expansion and accurate as anything in a 44 mag and a 357 mag. We love em here. Oh... and we have no choice in the matter in CA anymore. No Lead Allowed. It's always funny that people will spend so much on gear/knives/guns/hunts, but won't spend an extra 50 cents per round on the item that actually does the killing!!! The xtp is a good bullet but the barnes is the best. However dead is dead and its more inportant to put it through the boiler room than shoot a premium bullet! We dont shoot anything but barnes cuz we feel they are the best, but thats just my oppinion.
