I currently don't own any large caliber rifles or custom guns. I am looking for a good 500yd elk(mountain hunting) rifle and I was going to buy a Sako Tecomate 300WSM, until I had a long conversation with one of my fathers shooting buddies yesterday. He has done alot of long range shooting(500- 1000yds), but not alot of elk hunting. He is trying to sway me towards a 7Mag Sendero. I have done alot of reading on hear and it don't seem either has a real advantage. Am i missing something? FYI-I will be reloading and hope to maybe shoot a little farther with some practice, practice, practice.
