Food for thought. I have a 300 Weatherby, Mark V Terramark, with a 26" barrel. I shoot Berger 215gr. Hybrids @ 2965FPS. This load is surprisingly easy on brass for me. If I do my part, this load shoots 1/2 MOA out to 800 yards. I haven't tested it further yet. Within the ranges I shot all I can say is this load is an absolute hammer. With the addition of an Accubrake the recoil is no more than a .308.
Now to respond to the post with a little more weight... I write this with tears, because of a new job I could not partake in "The Annual Elk Hunt" this year.
On Saturday, a friend of mine harvested a big 5x6 at 750 yards with a 300 Weatherby shooting a 210 Accubond LR. One shot DRT.
Sunday morning another friend of mine harvested a nice 6x6 @ 650 yards with a custom Hart barreled/ short throated 300 WBY shooting a 180gr Nosler Accubond @ 3230 FPS. One shot and the bull took a snow nap DRT.
Monday evening my friend's father harvested a 5x5 yesterday at 480 yards with a 1980's Mark V in 300 weatherby shooting box Nosler Custom 200gr partition @ ~2850FPS 1 Shot DRT.
I am impressed with all of the builds /chambering from various member within this forum. As far a myself and my hunting buddies, we are partial to Weatherby. In my experiences hunting and shooting from 50 to 1,300 yards I have not found a reason not to seek another cartridge.
Long live the belted magnum. And yes, you can bet your paycheck that this is the last hunting trip I miss!
