I need to make a cop friend.
There's usually some listed on gunbroker.
What caliber are you looking for?
.45 ACP lc
OH - So this stuff is LEO; do they ask for some kind of proof?
No, cvilians are able to buy it. It's just harder to find in stores.
Corbon DPX is good stuff too.
No just place your order and your'e good. The LEO only thing is a winchester liability thing.
Hm. I'm mainly interested in it because it performed best in the Box of Truth. I wanted to get some RTs and fire off the rest of my Hydra Shoks.
Get whatever you want. The RTs are good.
I thought DPXs performed the best in the BOT? Isn't that what that guy carries himself?
As usual I recommend anyone interested in learning about handgun defensive ammo performance read this http://www.firearmstactical.com/hwfe.htm and then either look up further information or start looking at gelatin tests on their own. The ranger t's are excellent jhps, but so are pretty much all premium rounds. The hydrashocks are federal's outdated design and I certainly wouldn't recommend them any longer. They'll work and the difference is probably marginal, but you can do better. Federal's HST has replaced the hydrashock as their premium round.
I'd go with 165-200g +p instead of the 230g +p Ts, personally. Speer, Hornaday, and Corbon all make JHPs in that range. I think Black Hills does as well.
Federal HST is pretty good shit too if you can find it.
Hm. Based on the information here:
(Well, bullet mass and estimated velocity) the +P load will deliver 25% more KE to the target. I suppose that also means 25% more recoil.
no, because KE is .5mv^2, while recoil is a result of the inertia of the bullet and getting it up to speed blah blah blah, but basically recoil is a result of m*v, not KE.
I forgot the 1/2 in my calculations. That makes it 20% more, not 25% more.
Nevertheless, don't forget Newton's third law. The KE in the bullet when it leaves the barrel = the KE in the gun. The gun is just a lot more massive than a bullet and your grip plays a big role in things as well.
negative ghostrider. 3rd law states that the same force acts on each object. They will NOT have the same kinetic energy (.5mv^2), but they will have the same momenta (mv). to figure out how much extra recoil there is for the +P in different weight, you would have to figure out the muzzle velocity of the round, multiply it by how much it weighs, then devide by the weight of the gun, that is how fast the gun would go without your hand, higher number = snappier recoil (note, a smaller number does not always mean less recoil, you have to take into account the mass of the gun, since a slow gun that weighs alot will still feel like alot of recoil).
I disagree. F=ma both ways, right? The "forward" force on the bullet and the "rearward" force on the gun are equal, yes? But the bullet masses a lot less and therefore the acceleration is a lot more.
Dangit, you've put some doubt in my mind and I'm too tired & lazy to work it out on paper right now.
