Paintball on next 'SAS desert'

[Skeet]

Hmm...I dont think a .410 would knock anyone over, even if they were standing on one leg!
My young daughter shoots a .410 with me...she is 7!
As for arching your back..I once shot a round of Skeet with a 12 Guage on my knees, to see how different it was and whether it was quicker...made no real difference to how I shoot, but my knees hurt after a while.

Recoiless rifles have been about a fair while now...my first air rifle was a semi recoil less, a friend had a Feinwerkbau, .177 match rifle as well that hada a recoiless action..so they arent new, but yes the action recoils into the stock...

MikeyR... I thought taht apart from the amount of ammo that can be carried in .223...that there were human rights people moaning about the damage that a round like 7.62 can do inside the body.....223 tends to stop when it hits something, where as 7.62 kinda flys around all over the shop...dunno, might just be something I heard somewhere!

The 7.62 damage thing comes from the old soviet rounds. They are designed with a core of lead that moves forward and unbalances the round on impact causing it to tumble through a target as opposed to just punching straight through.

I was under the impression that the 5.56 bullet was meant to "tumble" in tissue, so as to create a mahoosive exit wound rather than just pass clean through, with a similar idea to a landmine in that wounding a man removes more from action than just straigh killing them.

 

[Skeet]

Well...im not sure....depends on the head of the bullet, normally they are designed to stop the target, as a bullet going through you, doesnt do anything...if it hits you hard, you know about it...yes wounding is better than killing as it ties up more soldiers...I dont think .223 tumbles....but i know 7.62 does...very nasty, cuts you to ribbons if it catches the right bit of bone...pelvis is a good one, cxan end up coming out of your neck!

bullets

Tumbling has a lot to do with the injury pattern of a bullet on the target, A short, high velocity bullet begins tumbling more rapidly in tissue. This causes more tissue to be displaced and imparts more of the KE to the target. A longer, heavier bullet might have more KE at a longer range when it hits the target, but it may penetrate so well that it exits the target with much of its KE remaining. Even a bullet with a low KE can impart significant tissue damage if it can be designed to give up all of the KE into the target, and the target is at short range (as with handguns).


Most is dependant on casing copper/lead based hollow tipped and so on, generally damage is split into the following

Laceration and crushing - Low velocity bullets, as in handguns, that travel less than 1000 fps do virtually all their damage via crushing.

Cavitation - Cavitation is significant with projectiles travelling in excess of 1000 fps. A "permanent" cavity is caused by the path of the bullet itself, whereas a "temporary" cavity is formed by continued forward acceleration of the medium (air or tissue) in the wake of the bullet, causing the wound cavity to be stretched outward.


A bit of nice info (did you know that chambers on assault rifles and automtic weapons are built to withstand pressures of 60'000psi

Bullet velocity and mass will affect the nature of wounding. Velocity is classified as low (<1000 fps), medium (1000 to 2000 fps), and high (>2000 fps). An M-16 rifle (.223 cal) is designed to produce large surface wounds with high velocity, low mass bullets that tumble, cavitate, and release energy quickly. A hunting rifle (.308 cal or greater) would have a larger mass bullet to penetrate a greater depth to kill a large game animal at a distance.

For you info Skeet, The Hague Convention (and subsequently the Geneva Convention) forbade the use of expanding, deformable bullets in wartime. Therefore, military bullets have full metal jackets (to mention a film name) around the lead core. Of course, the treaty had less to do with compliance than the fact that modern military assault rifles fire projectiles at high velocity (>2000 fps) and the bullets need to be jacketed with copper, because the lead begins to melt from heat generated at speeds >2000 fps.

However, police departments, hunters, and assorted "bad guys" did not sign the treaty and may use low velocity handgun cartridges with bullets having a soft lead point or a "hollowpoint" designed specifically to deform on impact. Such deformation imparts all the KE of the bullet to the tissues in a short distance


Sorry I got carried away............. no wonder Mi5 wouldnt take me

Makes 300fps gelatine spheres that collapse on impact sound a bit tame, really!
