I guess I'll step in the poo again! This rumor of the 7mm problem was not started by a moron, at least how it originated with my experience is from old meat hunters that had no care in the world what they shot as long as it cleanly killed game without blowing a bunch of meat up, they had no care of science they just killed the game they needed. Not a singe one carried a 7mm, as in ZERO!!!! You can't just discount this when an old guy with more elk and deer under their belt than you'll ever see gives you his opinion, science no but a I'll take the life time experience of an old man over anything. Ya, I've given the 7mm a try didn't like it just like I didn't like others but if some one does good with one rock on!! I've all way considered my dislike of the 7mm mostly centered around the 7mm mag but I've never called any one a moron for using one if it worked good for them, unfortunately most of the guys I've dealt with over the 7mm has been helping them figure out why it won't penetrate an elk shoulder or why it blew a front quarter of, it is usually easy to find the problem which is a poor choice in factory ammo which may be what the old guys had going on as back in the day they did not have the excellent array of bullet we have today.
Most my problems have not been dealt with scientifically, I just don't like belly crawling out to the middle of a circle to try to single out one wounded elk out of 800 head, I don't ask much more than what the heck your shooting and where the heck were you aiming. The last cow took that was wounded that I had to get took three days of belly crawling down fence lines and pivot tracks trying to get her singled out and killed, kinda sticks in a guys mind lightbulb
Now I'm going to have to mill a bunch of 7mm and 270 bullets in half just to see if there is a difference.
Winmag, remember the days when guys like us were just ranch hand local guys, now we graduated to red neck morons, a guy needs hip waders in this thread but oh well. By the way had several hundred head of elk just outside Jackson and I forgot to take my tags to work with me and the rancher wanted me to go take a couple home, it's the time of year to take the rifle, tags and orange to work!!
