I would say it's a .300 Win. Mag. as you can shoot as low as a 110 grain bullet, and up to a 220 grain bullet with plenty of knockdown power for even an Alaskan Brown.
I use 180 gr. Nosler Partition, Reloader 25 powder and magnum primers. My rifle ( a custom commercial mauser, B & C comp stock, Shilen SS match bbl) likes 86.5 grs. Sierra Game King 180 BT also shoot well, but the partitions group slightly better. Both do sub minuite groups out to 500 yds. Rifle is topped with a Leupold VXIII 4 x 14 40mm with a custom ballistic turret from Leupold matched to my load.Colorada Cowboy, Hey whats a good hand load for the .300 Wby. mag for elk? I just picked one up this year and so far I love it! I too have used a 30-06 for many years and it has served me well.
Love my 7mma 7mm Rem Mag, both are really good. Plus, if you are ever in a bind, it would be much easier to find a box of 7mm Rem Mag ammo.
Most Weatherby rifles in 300 Wby. are a little bit heavier guns. A heavy gun tames recoil pretty nicely. My Remington Sendero 300 RUM is a pussycat to shoot.Thanks, Colorado Cowboy and Bitterroot Bulls. I will see what I can work up for my .300 Wby. As far as recoil, I am impressed at how mild it is, I was expecting alot more. I have only shot Wby 180 gr. factory loads so far but what a smooth shooter! My 30-06 is a Win. model 70 featherweight and it kicks more.
