I own a remington 700 BDL 7mm rem mag. very accurate gun. I want a gun i can hunt with for moose and elk and whitetail at ranges out too 700-800 yards and accurately shoot targets at ranges well out and over 1000. The reason i want 700-800 yards is because where i hunt moose the max shooting is around 600-700 yards and i want to just take it to about 100 yards past that incase of anything at all. Dont want to loose a trophy bull. I know that loaded properly a 7mm mag can do what i ask for it but im not sure if its really the proper caliber for the job. I do not want a 338. I dont think i will put it to full use. Most of my shooting is between 50-600 yards so i know a 338 isn't needed. I dont know what caliber will be best for me. I own a 300. wsm and absolutely love it. The only issue is, its a browning a-bolt so i cant do any work to it. It is accurate enough to take the game i want at 600 yards but not any further then that. and if i wanted real precision i cant get that out of it. Its strictly a hunting rifle. I was debating turning it into another 300. wsm. This caliber is more adequate for ranges im talking about and in a long action i can utilize the 190-210 grain bullets. I know there is no point in shooting the short mag if im talking about 190-210 when the 300 win mag does that naturally. the reason im considering it the most is cause i already have everything i need to reload including 100 empty shells 1 fired. The wsm will do everything the win mag will in a long action. the only other caliber i was considering was the 300. RUM. If i were to step away from the wsm why go to a win mag if just a step past is the RUM. What is everyone's thoughts?
