I sure would appreciate some experiences and opinions: I am considering putting together one of the 7MM rifles for a mule deer, elk & pronghorn rifle. I live and hunt mostly in the East but I am preparing for a couple western hunts in the next few years. I look at the reloading and bullet performance data for the 7MMs and it leaves me with a lot of questions. My goal is to develope a balanced and reasonaable rifle for practical western hunting. It isn't my desire to have a gun capable of the longest shot to ever possibly present itself. The RUMS use from 90 to 100 grains of powder with a barrfel life of 1000 rounds but they apparently kill at phenominal distances. The regular 7 MM Rem mag uses a fraction as much powder but still achieves very respectable Velocity. From what I read the recoil difference is also very significant. What is the difference in effective killing range and is it really worth the additional powder, barrel wear and recoil punishment? I want to balance recoil, powder used, barrell life, attainable velocity, killing range etc. I haven't hunted out west but based on all of my reading I think I could settle with a good shooting 800 yard rifle. It seems to me that I could spend a little more time to get within this range and still get lots of shots at desirable game. What are your thoughts? What is your experience? Which of the 7 MM calibers would you be inclined to select? 7 MM Rem Mag, 7 MM WSM, 7 STW, 7 RUM, 7 Weatherby Mag. etc. Thanks for any and all input.
