Hi vs. Low Velocity
« on: February 17, 2003, 11:45:47 AM »
My shooting buddy and I have concockted a theory that goes like this...

With a 45/70 load, muzzle velocity around 500 fps, a bullet will take 1.2 seconds to impact on the 200 yard berm from the time the shot is fired.

With a 45/70 bullet in the 1150 fps range, the time to impact on the same berm is 0.52 seconds.

Therefore, one could fire the 500 fps bullet at the 200 yard berm.  Within one-half second, the gun could be cycled, aimed, and fired with the higher velocity bullet.  According to the calculations, the bullets will impact at about the same instant.

With practice and a hotter second load, the second shot could be made to impact first.  A good spotter could tell you which bullet impacted first based on where it lands on the berm.

Empirical results of the above theory will be posted.

How about if you use that second shot to hit the first bullet before it hits the target.   KN

Of course...

the second bullet (the faster one) will impact well above the slower bullet on the berm.  The point is not to hit the same spot, but to see if the second bullet can be made to impact first.  Therefore, no sight adjustment would be necessary.

After sleeping on this idea, it occurrs to me to be dang sure that the first bullet (the slow one) has actually exited the barrel before firing the second one.  It's not that I'm fast enough to fire the second bullet with the first one still moving down the barrel, of course, but it will be important to make sure that the first bullet doesn't lodge in the barrel before the second one is fired.  I've made that mistake once...

Reportedly, the military practices this with howitzers, aiming the first shot real high for a long hang time.  However, their target distance is considerably longer...

KN, we actually discussed trying to hit the first bullet with the second.  However, our range rules prohibit us from shooting at metal targets.

Test results to be posted.

Big dissapointment.

The 405 grain bullet over 3 grains of Bullseye wouldn't make it to the 200 yard berm.

Back to the drawing board...
