For the last couple of years I have just purchased a cheap box of 30/6 and 25/6 ammo and have been successful deer hunting. But I also have missed some where I thought there is no way I should have missed and also at the range it seemed like there was a flyer every now and then, even when using a led sled. So, my question is, do you think it would make a difference if I upgraded the bullet? How do I know what is a quality bullet? Do I just need to drop a bunch of money to figure out which bullet fires best from my rifles?
