My hunting partner is kicking around getting a new rifle, which was the easy decision making part, now it is down to caliber. He is looking at either the 7MM MAG or the 300RUM,and this will be in a remington sendero. Now, if it was up to you guy's which caliber would you pick and why?
For me, the 7 is perfect. I don't need the extra whack of the RUM, and it will be a significant increase. Even the 300Win is an up from the 7. I shoot my Colt Light Rifle pretty good, but the Sendero in 300Win I shot, grouped well, (only 3 shots), but was not something I want to do much.
I think, therefore I am, conservative.

The answer depends on what he wants to do with it. Deer at 500-600 yards is different than elk at 1200 yards. How well does he handle recoil? Does he reload? Distances? Intended use? Shooting experience? A few more details will garner better replies. Bruce
Unless your friend has handled many higher recoiling rifles a 300 RUM might be a poor choice. I know several occasional shooters who are afraid of their 7 rem mags! IMO recoil is the biggest factor in this decision.
I'm gonna go with the 7mag mostly because thats what i have, and loaded properly that caliber has a surprising amount of range. 300 ultra mag is a step up, you can launch a 230gr in the nieghbor hood of 2900-3000fps, that is a helluva reach. Most schooled lr shooters can't take full advantage of that, but i does call for a break, and has a shortened barrel life. my opinion is get the 7mag learn to really stretch it out, then he could step up to the big boys in the class of 300 ultra - 338 lapua, and hit the ground running
Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.
