    I really like the 300 WM and as I am still looking to get a custom rig.I was toying with the idea of the 7 RUM.Wat do you guys think? How about barrel life between the 2 also.

    two totally diffrent cartriges. The 7 is going to be crazy fast and flat with hogh b.c bullets and about 900 rounds barrel life.
    The 300 win is gonna be about the same recoil, hit a bit harder because of frontal cross section, have alot more drop/drift but... about triple the barrel life.

    I've had a 300 win. I have a 7 rum. win ran 180s at about 3120 with a max load in a 24" bbl. Back when I first got the 7, I had a lot of RL25 that would push the 150 partition at 3500 with good case life for an ultra-The primer pockets stayed tight for 5 loads. The next lot was not the same...nor has any other been since. never approached that velocity again safely and accurately with RL 25. I have ran the 140 AB as fast as 3580 with retumbo but wasn't very accurate at 1.4 inches at 100 yds. And even though the pressure seemed ok; I was scared of the charge weight I was dumping into those cases. I settled on 7828 at about 3400 for a good mild accurate load. It also shoots the 160 AB pretty good with retumbo at 3250 fps. I decided to quit screwing around with loads and just settle on one and use it... thus the 140 ab load. I have approx 700 rd thru that 7 so far... still shootin good so far...always have shot 3 and let her cool. run a snake thru her every 3 shots.. clean her every 21.

    It don't get no simpler than that! With the .300 Win Mag, you'll have plenty of choices in brass and bullets (esp. in the 200+ gr) too.

    At $300-$400 and up a pop for a blank barrel + smith re-barreling cost could certainly up. The last re-barrel cost for me was $375 for the barrel and $250 smith cost. If you require muzzle brake, it's ~ $100 thread and install (not counting the brake). And since .300 Win Mag is about triple, that's ~$2,250 cost (unless you can do the smithing yourself) over the 7MM RUM you need to consider. But it that's within your budget, then it might not be a factor for you. I have limited funds for hunting/shooting, so it's a factor for this budget conscious member ... just saying.

    Good luck!

    I would normally say go 300 win but with the 195 eol coming out that woud be a ballistic monster pushing that bullet with its g1 bc of .794 at 3150-3200 fps

    if its only going to be hunted with...like 20 rounds/year, the 7 RUM is awsome. but deffinatley a hot rod.

    300 win is a king of practicality.

    I love my 300; got another 500+ yard trotter this year in the prarie wind. I use a 165 at 3300 fps out of a 26" barrel. I like the 7rum also and have my two longest kills with that cal. 140's at 3500 are monster for point and shoot without el. correction.
    I spot and stalk for the most part, so I don't play with some of the LR gadgets that the guys that sit have. I value speed a lot and don't care nearly as much about BC; I want a quicker mid range time of flight and will put up with more arc or having to close in a bit to get the time of flight down.
    You do need to be aware that the 7rum will flat out eat barrels. My 300 win has a bunch of rounds on it and it is still virtually new inside; I would have wiped out two 7rum barrels by now.
