[QUOTE="Kris S, post: 386709, member: 24801"] Hi LTLR, I'm afraid that saying that the 8x57mm JS isn't good for long range shooting is to seriously misguide people, I don't blame you however as most Americans know little about this round. Part of the problem lies in the fact that US manfactured ammunition of this type (8x57) in general is way underpowered, not even approaching exploring the true capabilities of this excellent round. The way to go is full power European ammunition, where you can easily get 200 gr bullets doing 2,700+ ft/s through a 23.5 inch barrel no problem. Fact of the matter is that the 8x57mm JS round is infact quite a good long range round, as long as you use the right type of bullet. It was infact long range lethality that the 8x57mm JS became famous for. During WW2 the 8x57mm JS seated the 198 gr sS FMJBT projectile, the most aerodynamically efficient rifle bullet of the entire war with a G1 BC of .593 at supersonic speeds and .557 at subsonic speeds (That's considerably higher than a modern .308 M118 sniper bullet). With a typical muzzle velocity of 760 m/s through a 600mm barrel this tranlates into a 1,000+ meter effective range, the bullet still traveling at Mach 1.07 at 1,000 meters under International Standard Atmospheric conditions. This bullet enabled German machine gunners to engage Allied troops out to 3,500 meters in the North African desert during WW2, leading the British to sometimes believing they were under automatic cannon fire. Furthermore German snipers recorded confirmed kills out past 1,100 meters with this round (ex. Matthäus Hetzenauer). Today you can still easily duplicate this performance by either handloading, purchasing select european ammunition or WW2 German surplus.
