Jacketed hollow points, on the other hand, tend to strike something of a happy medium. Mono rounds, as it happens, tend to be long on penetration and short on expansion or the opposite. The hydraulic pressure causes the trocars to break off and the solid core keeps going.Īdditionally, since they are solid copper, that means they are monolithic in that they're made of a single material. In the broad strokes, RIP rounds are more or less fragmenting or frangible rounds. Thus, G2 RIP rounds are a variation on a theme, just with external cuts and spires rather than the internal relief cuts commonly found on CorBon and Super Vel ammunition. This is why the 115-grain +P and +P+ loads were the standard for 9mm rounds for so long, despite conventional wisdom favoring heavy-for-caliber (eg 147-grain) loadings instead. They followed the same basic formula, making light-for-caliber +P loads that would penetrate deep and reliably expand. Unfortunately, tax problems forced the company into shutting their doors in the mid 70s, but companies like CorBon and others followed soon after. 38 Special loads being popular with law enforcement. Super Vel started making ammunition in the mid-60s, with their 9mm or. Those ammunition makers figured that same idea decades ago, making light-for-caliber hot loads that would reliably penetrate and expand. Some of you might remember or have heard of Super Vel or CorBon. How do you do that? Load a lighter projectile and put a bit more powder in it. What a few ammunition makers figured out is that you could get reliable expansion by making a bullet go a lot faster. What G2 Research did with their RIP rounds is to introduce a new take on an old concept. Too heavy a bullet at too slow a speed won't expand because there isn't sufficient hydraulic pressure.Īgain, this isn't new information handgun ammunition makers have been tinkering with this stuff for a long time. Too slow, and it just stops barely past the surface. Too light a bullet at too fast a speed goes through soft tissue like Congress goes through the national budget. However, you also need enough velocity to get the round to expand more velocity means more hydraulic pressure as it enters tissue, but - again - you also need a certain minimum threshold of mass in this regard as well. You need enough mass so that enough energy is retained by the projectile as it enters the target to inflict sufficient trauma and penetrate to sufficient depth. This isn't new ammunition makers have been tinkering with this stuff for a long time. So, the thing about expanding ammunition is that you're looking for a balance of factors in order to get the effect that you want from the bullet in a squishy target. The external channels and spires are new, but the basic idea - light projectile at high speed - is not the first of its kind. As the philosopher RW Hubbard observed, it sounds nasty and it pretty much is.īefore we go further, it bears mentioning that RIP rounds are basically a new take on the high-velocity hollow point. In theory, this means that the core of the bullet gets deeper penetration, but the trocars break off and puncture vital structures like organs, veins and arteries and so on. However, since copper isn't as dense as lead, it doesn't retain energy as well as a solid lead projectile and thus comes to a stop sooner. The trocars slow down rapidly, coming to rest at a relatively shallow depth while the core of the bullet keeps going. The intended effect is that when the round enters a fleshy target, the spires peel back and break off into trocars. They aren't making a novelty round for the sake of it this is serious ammo. Their bullets are CNC machined for quality control, so - anything else you might think aside - their process is geared around consistency. I actually spoke with the factory guys at SHOT Show. This leaves a thin web of copper between the vertical spires that are created by machining the projectile. After casting, horizontal cannelures are cut into the projectile, followed by vertical channels cut into the projectile. The bullet itself is a copper hollow point, with a crowned nose kind of like Winchester hollow points (Black Talon, Ranger, PDX) though obviously with much sharper points.
