Grizz--

If I understand the theory above properly one should be able to shoot a "lighter" heavy bullet faster and get more penetration without excess pressure due to the bullet bands.

I guess another real concern would be whether the lighter banded bullets would regulate properly in my Double at a faster velocity. My Woodleighs are great. Be nice to have faster deeper penetrating solids( a 540 gr @ 2200fps? ) that regulated well too!!

Anytime I can get a free lunch(FN bullet, more penetration, same energy)) with technology I want it!!
