Thread: Longest confirmed kill @ 3.450km

Please can we speak in real measurements.
They haven't made feet and miles since 1966.
That's 51 years to adapt to a much smarter and simpler system, we drive land rovers we must be at the forefront of human evolution .

I fired a .50 Barret once - you could actually see the projectile disappear into the distance. Had a really high trajectory even at 1k, would've been aiming like a mortar at 4k.

lol true, though its just 'easier' to talk inches, feet and yards in regards to MOA...though I suppose we could talk metric if we talked mils instead. maths was never my strongest game hehe

I still prefer mpg, ft/llbs, and hp. Much prefer the linear mm, cm, and metres though. Being divisible by 10 or 100 is appealing. But being in that 'in between' age group...I love it that on the common measurements, I have a built in memorised conversion factor from childhood...eg 3.281 ft to a metre, 1.6km to a mile, 4.5L to a gallon etc.

I wouldn't worry about using a 700 yard zero Andy, better using 100 yd for charts, makes it easier to work out for setting up balistics computer...


Just as much energy as a lot of calibres have at the muzzle... the 300 wm drops around 134 inches at 750 yards with 150 grain projectile(muzzle velocity 3100fps) and drops 148 inches at 750 yards with a 178 gr projectile(muzzle velocity 2900fps)...

The cheytac375 has better balistic characteristics simular to or better than 338 Lapmag...

The drop factor is not much to bother with, its the amount of retained energy thats required to maintain accuracy... the drop is taken into account for the target, but if the energy is down to about 100 ft-lbs then a puff of wind would send it off course easily...Same as a heavier projectile means retained energy, thus the .50bmg has a long range for accuracy...

The 50bmg can use a 650gr to 800gr projectile, max velocities of 3000 fps for 650gr to 2750 fps for 800gr with muzzle energy around 9900ft-lbs for a 650gr projectile and around 14400 ft-lbs for a 800gr projectile... Thus long range with that amount of energy can give a very stable projectile out in the distance and still do its job...

A .22 LR can go through a persons soft part of the body at 3 k's, so dont be fooled that these large calibres have no energy left at 3, 4, 5, or even 6 k's...

The .22LR shot I am refering to, happened in Leonora, many years ago... A bloke fired at a crow on a tank, 3 k's from town, bullet went through the stomach of his friends wife, in town... it was a piddly .22lr using a subsonic... so dont presume the bullet has no ability to go far...Luckily the shot hit nothing vitale and they stayed friends over the incident... nothing has a safe distance unless its stopped and laying still, then its safe...

Fair point re the zero and charts wraithe - thanks mate. I was just using 700 as I doubt the sniper would have zeroed at 100 -perhaps more like 500 - but I was more interested to see drop in the calculator and randomly picked 700 :-)

Impressive numbers all around in regards to the rest of your post - I'd like to own a 300wm eventually -I've shot the .338 but not the .50.

And believe me, as a bow hunter, all of those calibres mentioned, including the .22 have more kinetic energy at 3km that I can get at 30 metres

Really?,a bloke shot at a crow 3km's away and shot his mate's wife,yeh OK. Pat

You may not believe it, but I was young when it happened, just bought my first rifle...He warned me that it can go further than you think...

When our friend reported to the police, with the possibilty it was his shot, they didn't believe him...

But right trajectory, and angle, from where he fired, it was his shot... I remember him saying, he was too scared to see his mates misses at the time until his friend came and ask that he go see her, of course all was forgiven, but everyone was astounded that a little .22 could travel so far... Technically speaking, it would have been as far as the bullet could travel, so dont believe these projectiles just fall out of the sky so close...

My son has put a round, 20 yards short of a 750yd target, inline with a 30/30... Another calibre everyone thinks is no good for more than 150 yards...

The idea of an effective range (or point blank range) is misleading, thats the range of shooting effectively for an accurate shot, not the ability of that projectile to not be able to travel further...

I use 4 inch point blank ranges, my 30/30 is good for 350 metres, the projectile travels 4 inch high to 4 inches low over that distance, thus an 8 inch diameter kill zone... makes it great for the blocks around home...
