How many of you have used 200 grain bullet in you 300's for elk? I have worked up some loads (200 grain accubond) in my .300 RUM but have not been out to try them yet. My brother in law shot his elk last year with a 200 grain accubond in his .300 Win. Is there any difference that you could notice between the 180 grain and the 200 grain. Of course to compare and be fair both would have to be the same type of bullet.
