I am looking to build a 7mm long range rifle and have yet to decide on which 7mm or who to have build the rifle. Long range for me would not be over 1,000 yds as many around here shoot and is more like 800yds and in for my considerations. I have a 300 RUM and a 6/284 so I am not interested in .30 or 6mm right now. Rifle would be for medium sized game, deer, antelope, javalina (ok they're small) and time at the range. The rifle must be able to shoot factory ammo so I am not looking at any wildcat rounds. I dont want to travel to a hunt find a missing box and have to borrow a gun or scrap my hunt due to lack of ammunition. I will play with fine tuning handloads but wont be building a rifle specifically for longer heavier bullets. So which 7mm? My plan started with the 7mm WSM but I have seen a lot of 7mm Rem Mag and SAUM users around as well and a few that have said just go with a non-mag round .284/7mm. I was staying away from the big cases such as the 7RUM based on a lot of negative feedback on barrel life.
