On a side note Mr. Proffesor, and your pupil, both of you get an F on your energy equation! KE=1/2MV²!

However, terminal effect wise, a heavier projectile will retain more velocity at range and will penetrate more deeply than a lighter projectile, all other things being equal. Also, as I recall the bullets of the 150-grain range tend to have a higher BC than their lighter counterparts as well, so you loose less energy over distance than the lighter 122gr projectiles.

...can't believe I left that out...and nobody else noticed. Thanks, it has been fixed.

Hey now...no ragging on the pupil here

I failed HS science, okay? Never was quite my thing...

No excuse here I excelled in mathematics, the sciences, and engineering...well until yesterday...but it was late.

At the risk of going OT...I was a History/Athletics guy. But I did have a special place in my heart for Architecture...don't ask.
