I think sometimes we are " picking nits" on these threads. Truth of the matter is for 90% of the hunting any American hunter will do on this continent....it doesn' t make a squat of difference if you stick a 150grain .277 caliber bullet through the lungs, a 180 grain .308 caliber bullet through the lungs, or a 210 grain .338 bullet through the lungs. (Or for that matter you fill in the weight and caliber!)

If the velocity is sufficient for you to accurately place " said bullet" through " said lungs" and comparable expansion between " said bullets" occur.....the animal will expire without too much fuss. And in the final analysis any thing more than that...is just that, superfulous.

But hey....this is all about what makes you happy!

Rob2974....pick the cartridge that appeals to you most....I doubt either will dissapoint!

Good luck!
