I work at general Dynamics, making the explosives and the powder required that goes in the .50 Cal primers, and other military caliber. I can hear them shooting at the range a few times per day (indoor range) They have to ''proof'' each and every lot we manufacture to make sure we meet the Nato standards. I love my job !
One of these guy from Canada works with us now to develop the ammunition,i won't name him . Here is some cool info : Confirmed kills 1,250 m (1,367 yd) or greater
This list is not exhaustive, as such data is generally not tracked nor managed under any official procedure. For example, the Canadian Army 2002 sniper team that saw two soldiers (Arron Perry/2,310 m and Rob Furlong/2,430 m) set consecutive new records, also made a number of kills at 1,500 m that are not counted here. The list also shows that, in some cases, an armed force command may choose to withhold the name of the actual sniper for security reasons. The United Nations Security Forces, such as in the Balkans, also had one American Sniper (name withheld) attributed with a 1271-metre shot.
While not on the list due to the range being less than the minimum distance used to compile it, Hathcock's second-longest confirmed kill was 1,200 yards (1,100 m) using a "standard" USMC sniper rifle chambered in .30-06 Springfield. At the time of Hathcock's service, snipers had essentially been eliminated from the USMC, and its sniper rifles were a hodgepodge mix of commercial Remington 700 and Winchester Model 70 rifles chambered for multiple cartridges. The major challenge for Hathcock and other scout-snipers was improving the performance and reliability of their rifles and ammunition.
My buddy is a crew chief on the A10 Warthogs in the Air Force, think that one has a 30mm gun on the front. That thing is crazy, literally shreds things up on the ground. My buddy said the plane has to be at a certain angle and speed to fire the gun off for so many seconds as it literally slows the plane down.
It's pretty crazy all the weapons the military has nowadays, of which I'm sure we don't even know about half of them. I'm glad they have all that stuff, keeps us all safe over here.
