Dinosaur? Hell yes I'm a dinosaur too! And proud of it. It has taken me years to get comfortable in my own skin, having spent countless $$ to make sure I had the latest greatest and most popular or exotic gun, and the most updated designer ammo that was guaranteed to be the better than the last umpteen end all offerings in bullet design.
Through my satisfying myself with the effects of common simple bullet designs on medium and large game over the years, I have decided for myself with no reservations, that effectiveness of ammo on caliber has more to do with proper penetration and placement than energy figures and flowery expanded bullets.
Being a dinosaur has it's advantages. It means you can finally just be happy with the things you like, secure in your knowledge that it will work for you, and be done with the search for giants, mythical creatures, and magic bullets and calibers.
