Re: 7mm RUM?
The only truly successful member of the RUM family has been the .300. The ultra mag's hold to ton of powder and reach way out there, but real world gains that the ultra's have over more common, balanced magnums like the .300 Win and 7mm Rem are minimal. Plus, the ultras are really overbore, especially the 7mm and 300 (the 338 and 375 are more efficient, but still not great). they do best with AT LEAST 26" barrels, with many custom guns made with 28". They have their place in the shooting and hunting world for those that really want them, but their advantages for hunting only come into play at ranges that animals shouldn't even be shot at in my opinion.
