Re: 7mm RUM Re-barrel Options?
Some guys (myself included) have to learn from not one but TWO burned out barrels before we decide to suck it up and go with a larger bore.
The fact is that the 7RUM is freakin awesome on paper. With it's super high BC bullets and hyper velcoity it is easy to become mezmerized and hypnotized by it's mystical charm but in the end, it leaves us broke and frustrated.
Think of all the bullets, powder and primers you could buy for the price of one 7RUM barrel. By the time you have it fluted, shipped, chambered and braked youre in the $1K range. For what? A high BC bullet that get to 1K yards in about a second. The 7RUM will conquer the throats of those smooth custom barrels as fast as they conquer a deer at 1K yards. It seems like alot of money, pain and frustration for a shooter that wants to draw the line at 500 yards. For a 500 yard gun, you could even have a short mag that would last you 2500+ legitimate rounds AND cleanly harvest anything in North America with the exception of the largest of brown bears out to 500 yards.
The 338 Edge running 300 SMK's at 2800 FPS will be within 2" at 1K yards in a 9:00 wind in a full 10 MPH wind of a 7RUM running 180 VLD's at a extremely optomistic 3300 FPS. You will buy three 7RUM barrels for every one 338 Edge barrels. Many will argue that they are both good for 1000 rounds with the 338 maybe going 1500 rounds. Maybe physically that is true but dynamically there are not going to fare the same at all.
Good luck with whatever you decide. I am not trying to beat you up for your decision, just hoping to make you aware by sharing an experience from a guy who had 2 barrel burners and ended up very frustrated in the end with both.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
