    700 yds is a chip shot for either caliber. If that's the max range that you are going to be working in, then I would shoot the 7 mag for the high bc bullets, flatter trajectory, and about 30% less recoil, not to mention less powder consumed. You will be happy with the 7.

    Lots of variables to take into account here. When breaking it down you need to compare apples to apples and it's hard to do because each chambering shines in different areas.

    Either one will be more than adequate for your needs. For higher performance for the recoil produced, the 7mm Rem is the one to go with.

    The biggest difference when comparing the two comes down to Ballistic coefficient. In general terms. When comparing the 7mm Rem. with a 168 grain bullet with a 300 Win mag with a 168 grain bullet, the 7mm will deliver higher amounts of down range energy with less wind drift than the 300 Win mag because of a higher ballistic coefficient.

    This effect takes place until you start getting into the heavier, high BC bullets in the 300 Win. At that point the recoil in the 300 Win is a lot less forgiving.

    Both would work. 7 has less recoil, but 300 wins in every single other catagory when its an apples to apples comparison...
    High b.c. to high b.c. -300 (for 6-700 yds you don't need high b.c. tho)
    Largest bullet selection to fit any need -300
    Momentum catagory is also cornered by the 300
    Use a muzzle break if recoil is a concern, & you just plain & simple walk all over the 7mm.
    Unless somebody recently came out with yet another bullet for the 7mm to try to compete against the big 30's there's just no contest.
    Depending on your situation, either could best the other with this statistic or that, depending on how the stats are used.
    There are plenty of perponents for each side of the fence. Each figures thier side of the fence is the right side.
    It all comes down to personal preferance. Pick one that suits your personal needs, & hunting style, & be happy with it for its positive characteristics in your chosen criteria.
    Both will work, as previously stated, but I'm a 30 cal diehard. Just never been a fan of 7mm's in any configuration. Sorry.

    Either will work but the 300 winchester is the best if you want the best of the two. Just get on jbm ballistics and check all bullets/velocities and see which one you like the best. Run say a 150 grain 30 cal at 3500 fps next to a 168 grain 7mm going 3050-3100 fps to 700 yards. Either will kill the deer. Or try a 180 cutting edge .57-.6 bc at 3200 fps against the 7mm. 190 berger against the 7mm with your choice of bullets. All will kill the deer just see which one does the best with your parameters. I hunt with a 300 winchester quite a bit. I own two 7mm remingtons that rarely get out of the case. My favorite 300 winchester is a tikka light at 6 3/8 pounds and does not have a brake. No problem for me with 180 grain bullets. I like the 300 because it is much more versatile if you decide to hunt something else in the future.

    Agreed. Less recoil and run the #'s comparing apples to apples using a realistic velocity.

    Thanks, I am leaning towards the 7mm.

    You could even drop down to a 6.5 for what you described.

    ...cheaper to shoot for and arguably more fun.

    But, if you ever plan to hunt bigger game or longer range you may want a bigger cartridge/caliber. Like others pointed out, it's a little late to second guess when you've got a trophy in the cross-hairs.

    Go the way of the " mighty 7 " and don't look back. I have and love both, but the seven will not let you down, and punch you a little less at the same time. Shoot the 168 Bergers, and they will make your head spin. The 300 is an awesome cartridge. But particular to your needs, the seven is perfect. AIM SMALL, MISS SMALL, 7 STW:)

    I have both, and in your case would go with the 7. What you described is an ideal situation for the 7. If you may possibly go after elk, then I would say 300. I shoot my 7 without a brake, but my 300 has a brake.

    i also have both ballistically the .300 win mag has the advantage as if you follow the armys loading for the 220 grain match king but substitute a berger 230 grain tactical and drop a couple of 1/10s of powder you can get 2800 fps in a 24" barrel, a ballistically similar load in 7mm (200 grain vld) you'd be lucky to get 2750 at the same pressure (which is high) down range energy is also higher in the .30o. lets face it the 300 is a larger caliber as calibers goes up so does the volume or s.d. if your looking for a more comfortable light weight rifle to shoot than the 7mm has the edge but only in comfort not in the things that make a long range hunting rifle. a break can make a .300 shoot like like a 243 so recoil can be negated also. i shoot both and like both but the 300 is my long range hunting riflegun)

    Sounds great. And, your point is very relevant if you want to shoot an Elk (or larger).

    However, you're suggesting that bullet weight is the only way to compare apples to apples. As such, then a 168gr 30 cal won't stand a chance against the 168gr 7mm on paper. Although, it'll still be adequate to get the job done.

    A 168g Berger will smoke deer well past 700 yds.

    And, the average guy is likely to be more accurate/precise with a 168gr 7RM than with a 230g 300WM.

    Both are great cartridges and everybody should own one or both.
