    Bullet weight,..distance,...muzzel velocity,..all play a role.

    The 7mm ultra with a 162gr a-max is hard to beat. The 300win is a bad * round,..but IMHO the ultramags have the game locked down in spades.

    a 180gr pill from a 300win vs a 160gr pill from a 7mm ultramag may be fair,..but when comparing comparable bullet weights,..the 7mm has a higher BC and higher sectional density. This matters for long range,..but out to say 400yds,..I doubt you see a nickels worth of difference between the knockdown power. The Ultramag in 7mm with a 140gr pill will outshoot (trajectory) a 22-250!!!!!! That is witness to the power these ultramags have. Load them right,..and they are second to none. I have a buddy that sends whitetail for a dirt-nap at 700yds on a regular basis with the 7mm ultramag from a 26" tube. And best of all, belt to deal with. I am sure others will disagree,..but I think these big cases are the best thing to happen to rifles for long range since stainless steel!![8D]

    why chase the game when the bullet can get em from here?....

    The 7mm Ultra has more speed and energy.

    The 300 win using a 150 grain bullet has 400 less enegry at 300 yards then the 7mm Ultra using the the same bullet in a 140 grain.

    The only advantage of the 300 win is it can throw a bigger pill.

    I have read many of JustC' responses in these forum and respect his opinion. I have recently purchased a 338 RUM...WOW! Now I do want a 7MM RUM. These cartridges are great!!

    Don't forget about the full-powered 7mm STW too. The STW, while not all that common, is a great round and the ultra was designed to match its performance. I know Remington has/had factory guns in this chambering. I have heard that the STW can be loaded hotter than the Ultra, but I don't reload and haven't done the research on these cases to know (so take it accordingly).
    That said, I chose the .300 Win Mag for its higher knock-down power. If it's good enough for the Marine marksmen team it's more than good enough for me...

    Of course rusty1 you could always go with the 300RUM.

    During the week of Nov 19-22, my son and I were Deer hunting.

    After 2 hours of ardous 4-wheel driving trying to find Deer, we stopped for a snack.

    My son said "Dad, my 300UM can out shoot your 300UM Sendero." So we picked a spot...a wayyyyy out there... The spot was a Soapweed (about 3 feet in size, very dark green) in a patch of light sand at the base of a high Sandhill.

    He fired and hit it, I fired and missed it...his eyes are 20 my eyes are 57 with Trifocals. Then he said "let's see how far the shot was".
    I cleared the trip odometer and we drove at 4-tenths of a mile we came to a fence with no gate. "our" shooting spot was 200 yards on the other side of the fence!!!!!

    Give me the 300UM, 308 dia 180 grain anytime...

    conclusion: with a 300 UM if you can see it you can kill it...
