At the other extreme if you push one too slow it won't expand at all and will over penetrate. ![]() More modern designs tend to operate over a much more constricted range, and if a modern hollow point is pushed too fast, it will too rapidly expand, over expand and then actually reduce penetration and/or fragment. It's also what makes the XTP hollow points a good choice in marginal calibers like. That's what gives the XTP hollow points in general a very wide useful range. That was by design, as Hornady was going for a bullet design overall that would meet the FBI's 1.5x expansion requirement without going over board, in order to maximize penetration. It's a pretty wide range, but in general the XTP bullets are designed to expand to 1.5 times their original diameter in more of a "smoosh" mushroom shape rathe than in the nicely photogenic and jagged looking star shaped jacket prongs you see in newer hollow point designs that expand to 1.6 to 1.65 times their original diameter. 32 caliber 100 gr XTP is 800 fps to 1800 fps. Hornady indicates that the velocity range for the.
