Flat trajectory. Massive downrange energy. Sub MOA accuracy from many rifle and handload combos. High but manageable recoil in most rifle weights. Almost unlimited bullet selection, and widely universal availability of factory ammo, if needed If you were on a trophy hunt for big bulls, could you really come up with a better choice? For myself, the next bull will fall to another TSX, 165 or 180 gr, with extreme confidence. Why undergun yourself with lesser armament, or overrun yourself with higher recoil? If Roy himself were around today, I'm guessing he would endorse his 300 as perfection on elk.
It's still a .30-caliber bullet launched faster than some other .30-caliber guns. You can do the same with a .300RUM, and several other and equally faster .30-caliber rifles. You can also kill just as dead with a .308. .30-06, and so on. All you have to do is to close the distance before you fire the rifle.
There are other calibers that have just as many if not more bullet selection. For example, the bullet weight for .33-caliber bullets start at 165 grains, and ends at 300 grains.
