The most kickarse cartrige

ok, as some of you may know, The WWII german tank the King Tiger had an 88mm main gun that was diff from the orginal tiger.(diff b/c it had a larger shell case, more gun powder) It shot a 22 pound projectile with a muzzle velocity of 3300 feet per second. Now it seems that all the high velocity ammo these days for small arms have very small bullets. what cartrige would be analoges to the King tiger 88? (extream velocity, huge bullet) the 5.56 NATO round has the high velocity, but its bullet weight is very small and consequently its muzzle engery is very low. i would guess it would be a 150 grain bullet with a long barrel and a muzzle velocity of 4000 feet/second, is that possible?

I believe Hornady makes something close to that in .300 Weatherby Magnum.

How about .50 BMG? IIRC, a ~650 gr bullet at ~3000fps?

There are a lot of cartridges that get much faster than 5.56x45.

** I bet barrel life wasn't all that long. **

A battletank isn't built for eternity either. The basic 8,8 Flak 18/L56 (56 lengths of caliber) was designed to engage aircraft at an altitude of 12000 meters. The Königstiger's KwK 43/L71 was an improved version of this. Wear & tear don't count in combat. I don't think it makes any sense to compare ballistic properties between artillery and small arms. The two are "playing" in different leagues.

yeah comparigng tank rounds was a bad idea, but how about this the germans had an AT rifle that was chambered for 7.92x94mm http://www.antitank.co.uk/images/792x94.jpg
it had a muzzle velocity of 4150 feet/second now the gun did weigh 27 lbs and the barrel was 47 inches long but they did use it

Using the Taylor Knock Out Formula, that 88mm round had a TKO of 251528.

A 150 grain .308 projectile moving at 4000 fps has a TKO of 26. So according to John "Pandoro" Taylor, the 88mm has 9674 times more killing power.

TKO is calculated by taking the velocity of the projectile in feet per second times the diameter of the projectile in thousands of an inch times the weight of the projectile in pounds.

There are 7000 grains in a pound. There are 25.4 mm in an inch.

So to figure the TKO of a 150 grain, .30 bullet at 4,000 fps:

4000 x .308 x 150/7000 = 26.4

An 88mm shell is around 3.46 inches in diameter.
