This is for my non-gun readers. The 5.56mm NATO round (SS109) leaves the barrel of a M-16A4 at 3100 feet per second.
Winchester is about to put on the market a .17 Winchester Super Magnum that goes 3000 feet per second.
Do you know what that means? It means that you're almost getting combat rifle performance out of a rimfire round (spare me the difference in bullet size and weight...you know I'm talking shot placement and a flat shooting rimfire on a nice trajectory out to distance never seen in a bullet of this type before).
Read about it here at Guns Holsters and Gear.
NOTE: Lets assume a modest effect range of 200 yards on a windless day. This round has applications for urban sniping. Even without a suppressor its report will be much less than a 5.56 or .308 and with the speed that its going with a proper bullet core it should be able to penetrate at least 1st gen PASGT helmets.
with enough velocity bullet size to an extent becomes less relevant does it not? einsteins e=mc^2 is relevant here, by increasing velocity (c) you get an increase in energy even with less mass. i am not a weapons expert thats why asking.
ReplyDeleteMore or less. That's the basic logic behind the Navy's "rail gun"
Deletei'm glad you answered Steven cause to be honest I had no clue. what i do know is that i've had shot placement, shot placement, shot placement screamed into my ear since i got out of pampers. they don't like to waste ammo in the country!
DeleteTo quote Wikipedia,
DeleteFor example, in the late 2000s, the U.S. Navy tested a railgun that accelerates a 3.2 kg (7 pound) projectile to approximately 2.4 kilometres per second (5,400 mph).[4] They gave the project the Latin motto "Velocitas Eradico", which is Latin for "I, [who am] speed, eradicate", but may have been intended as "Speed kills" or similar.

Wrong Formula (e=mc^2 is the energy = mass formula used in nuclear reactions).
ReplyDeleteThe kinetic (impact) energy formula is 1/2mv^2. The key here being that the velocity is squared which means that double the speed = 4 times the energy.
I knew it was the wrong formula, i mean "c" is a _constant_ after all, but honestly didn't know the correct one. Danke.
