The RUM will get you well past 1K maybe 1300-1400 yds depending on load, elevation etc. If I had a choice between the two, the RUM would get the nod. In fact, I've been considering the 7mm RUM vs the 300 RUM and just recently picked the 300 because this particular rfile is a proven tack driver. Otherwise, I was leaning to the 7mm. If I get another rifle, it will likely be the 7mm RUM.
I'm not sure what bad you've read about the 7mm RUM but I cant think of any. Barrels burn out fairly quick, but that's the same for any of the 7mm mags.
If you like open country, you will like the West.
ON the barrel burn out issue.
Any over bored cartrige will burn out faster than a standard one.
P O Ackley did a lot of testing on this problem and so did the military they both came to the
same conclusions that any round that exceeded 3000 ft/sec and was over bored (Like most
Magnums ) would be harder on barrels.
Powder erosion is the biggest problem with over bored rounds because a lot of powder gets
pushed out of the chamber and against the throat that has not burned yet.
Ball powder was developed to minimize this problem because it was though that the shape
was easer on the throat.
As far as the throat erosion of the 7mmRUM it will probably last 12 to 1500 rounds with good
loading and cleaning practices ( A lifetime of hunting ).
The heaver bullets will help with barrel life ( Lower velocity and more complete burn of
powders ) plus better BC for long range .
The big 7mmRUM was made for big bullets and will amaze you how accurate it is when set
up with the right powder and bullet combo.
