Okay, here's a good one for Oleg, Will, and the other 32ACP lovers on this board.
I've been doing a lot of thinking (yeah, I know, bad idea) about penetration VS expansion in my little P32 mousegun. From what little tests I've done, it seems like the 32ACP hollowpoints in 60gr persuasion just don't have sufficient momentum to create sufficient penetration. Even the FMJ ammo in 73gr doesn't have half the penetration of a 90gr 9mm Starfire HP. From what I've seen, the Fiochhi 73gr FMJ has the best penetration, even though I haven't gotten my hands on any S&B FMJ for comparison. from what I understand, these two brands are the hottest 32ACP FMJ available.
From all the things I've read about in mags and pulled off the net, with mouseguns the rule is penetration first, expansion second. Mouseguns just don't have sufficient energy for both. So if penetration is the first and foremost issue, I've come up with a theoretical bullet design that might have some merit. Tell me what you fellas think.
(1) It would be a +P round, ideally 70gr+. This would maximize kinetic energy from even the short barrels. However, I don't know if this is possible, because the heavy weight of the bullet might us up enough case capacity to make +P loadings impossible.
(2) It would be made like a partition-style rifle bullet, with a solid copper or alloy frontal section and a bonded lead rear section. However, the lead core would reach farther into the front of the bullet profile, approx. 75%, leaving 25% for the alloy "tip".
(3) The tip would be pointed, instead of rounded like a standard FMJ. Not pointed like a pencil, though. It would have a much more shallow angle from the point to the edge, perhaps 15-30 degrees, kind of like a drill bit without the cutting flutes. Like the point on a starting punch for metal. It would round off as it got to the outer edge where the bullet meets the case, to ensure smooth feeding. This would probably penetrate much better than a round point, standard FMJ through heavy clothes and bone.
Along the pointed face of the bullet, there would be linear grooves radiating outward from the center point, perhaps 10+. They would be like the linear grooves cut into the shank of a lug bolt. They would end where the bullet edge begins to round over, so as not to hurt the feeding and sealing of the bullet-to-case contact. The grooves would reduce the surface area of the bullet face, thus reducing surface friction and increasing penetration, like the dished-out cutting faces on a Muzzy braodhead.
What do you guys think of my late-night mousegun brain fart?
