.300 Ultra Mag vs. 7mm Ultra Mag

[spartan231490]

Hey, I'm new to the forums today. I actually joined because of this thread, as I am having a similar dilemma. I can't decide between the .300 RUM and the 7mm RUM, and with so many people having actually shot them I thought it would be a good place to get advice.

Most of my shots where I normally hunt are 60 yards or less, but I also get pretty frequent shot opportunities at 200 yards or so. Obviously, both of these guns are significantly more powerful than I need, but I've always been a fan of overkill, and I also want an ultra magnum for collecting reasons. I'm not concerned with kick, I'm a big guy and I go to the range routinely and put 2 boxes of 3 inch magnums through my 12 gauge.
A couple places that I've come across on the internet while comparing these two calibers mention that the Ultra mags are a little inaccurate at close range. Does this have any truth to it?
Also, how expensive are the magnum rifles. I only really have $1000 dollars at most to spend right now, can I even get an ultra mag for that much? I'm more than willing to buy used.
Finally, does anyone make a pump action rifle chambered for either of these calibers?

I would buy a Remington Sendaro in 300 RUM if you want a factory rifle. You can get a new one for $1100.

BigD's,

I like 180's so I went with the 300 RUM... two of my buddies had 300's and went to 7 RUM because they get a little better ballistics out of it with 160gr... A third friend even went back to 300 WM because he said that there was not enough gain by having a RUM over a WM... he shoots a lot more than I do. I have debated both but I just like a 30 cal over a 7mm. The 7mm 160 smokes my 300 180's and I have a little more drop at 500 yds than they do but all in all, they are both excellent choices. Recoil is about the same on both to me.
