    Is the 7mm Ultra Mag dying off?

    Have been thinking of getting a 7mm RUM, but ammo is not readily available. Even looks hard to find reloading equipment.
    Is this round dying off? Should a person stay away from this caliber?

    I would stay away from it. I don't think it ever caught on. It is so seriously overbore that my guess would be barrel life is super short, and you are burning through powder for modest gains o er the other 7 mags.

    If you were looking at it for flat shooting Maximum Point Blank Range rifle, I would recommend running a light hard bullet out of fast 30 (like a 300 Win or 300 RUM with a Barnes 150 TTSX).

    If you want really long range, the old boring 7 Remmy does well with the super high BC Bergers out to 900 and beyond.

    If you want to go even further check out the big 338s and a LR high BC bullet.

    I agree with BB. Plus those 7rums kick like a SOB in a light weight rifle. I'm pretty happy with my 7mm rem mag shooting the 180gr bergers for long rang shooting

    I think it never caught on well because it cant really do anything the old 7mm rem mag cant and there is alot more factory ammo available for the old 7 mag, plus there are alot more guns available chambered for the old 7 mag.

    I'd go 300 WSM or 300 RUM, depending on how much recoil you can tolerate. Of course there's nothing wrong with the old 7mm Rem Mag as others have suggested.

    I don't think that round is going away. Yes less factory stuff will become less available but you will be able to get reloading stuff for a long time. There not going to stop making 7mm bullets or powder. 100 pc's of brass will last you a long time as well. As for being over boar I guess you could say so, but for how long the barrel will last depends on how you take care of it. It won't be a varmint gun so you just have to keep the barrel cool. You can toast any barrel by over heating it. You should get an easy 1,000 out of it. How many can say they have shot that many rounds? It really depends on what you are wanting to do with it. It will really shine with heavier bullets. The RUM will push any bullet about 250-275 fps faster then the Rem Mag. So that means less drop, less drift, and more energy down range.

    The 7 RUM burns waaay too much powder. If you do buy one make sure you order a barrel soon as I would be really surprised if it made it to 1,000 rounds.

    So if I already have a 7mm Rem Mag and a 300 Win Mag, I probably not gaining anything with a 7mm Rum? Maybe I would gain more with a 300 Rum?

    Sure you are gaining something ... another rifle! I have calibers that essentially duplicate each other, and I still like them.

    If you want to add a caliber that doesn't duplicate what you have (actually what you have aren't far apart, performance-wise), I would suggest moving up to the 338s or 35s. Or ... add a varmint caliber.

    Except shoot the same bullets in factory loaded ammo 2-300 fps faster with something on the order of 10" less drop at 500 yards. I happen to like the 7 RUM, yes it burns a lot of powder, yes there is some recoil, yes it's loud and barrel life can be shorter than some other rounds. I don't think it's going away any time soon. On the other hand, I really think the average hunter would be better served with the plain vanilla 7mm Remington Magnum especially if shooting factory ammo.

    You didn't say what you want to shoot with it or how far you want to shoot, for deer hunting out 300 yards I wouldn't pick the Ultra but either a 7x57 or .284 Winchester. The .284 can go a bit farther than that in skilled hands. For the ultimate ballistic advantage in a factory loaded 7mm the 7 Ultra wins hands down, for an advanced hand loader the margin is even bigger.

    Just my $0.02
