The point is instead of worrying about adequate let�s talk about what is the absolute best elk cartridge in the world??
No such critter exists. My favorite elke cartridge that I have is my .375 H&H loaded with the Sierra 250 gr BTSP over a healthy dose of RL-15. With this load I would go out to about 400 yards.
There comes a time when one must take a position that is neither safe, nor polite, nor popular -- but one must ask, "Is it right?"
