Back to real elk rifles. There are 2 kinds....
Point and shoot....these are guns you sight in at 250 - 300 yds and just aim center of vitals to 400 and top of elk at 500 with practice. They are 300 win mag, 270 WSM, 7mm STW, 300 weatherby, etc. they all are big recoil hard to shoot guns and i find when i put a paper plate at 400 yards, their owners miss it!
With all due respect, my experience has been quite different. I'm 5'5", 155 lbs. I intended to buy a 7mm Rem. Mag. Browning A-Bolt SS LH, but the dealer had only a .300 Win. Mag. The first 30 shots from a bench with factory ammo were terrible: 1 3/16" to 4 1/8". First handloads: 3/8" to 7/8". The rifle consistently shoots MOA 3 shot groups with my best handloads (IMR 4831 and Nosler 180 gr. Partition Protected Point). I've taken elk with it (all one shot kills) and one small black bear in the Bob Marshall Wilderness (about 120 lbs.) at over 400 yards. Nevertheless, I honestly believe a .30-06 is the best cartridge for a hunter with limited mountain hunting experience (and I prefer a guide who discourages shots that are too long or too likely to be blown off by the wind.)
