Flinch, I hear where you are coming from. I currently shoot a 7mm Mag (have for 20 years...the same one in fact). My first forays into long range have been with a Remington VLS in 6mm shooting 95grain sierra HPBT's. It is a beautiful little rifle that I have learnt a lot with, I still have a lot more too learn. The 7mm with good 160'ish grain bullets is a tough one to beat no doubt.
Too be honest gents, I swing from the 7mm Mag to the 300RUM. Half the attraction of the rum is simply because I don't have one and it is a bigger cartridge. Ballistics wise, it almost seems like you could go 7mm and skip the 300 to 338. Both the 7mm and 338 appear to have ballistically superior offerings...though I am happy to stand corrected.
As I'm in no rush, the decision doesn't have to be made right now. Perhaps the 7mmRUM is equally worth consideration?
Experience is something you get, just after you needed it.
