.300 win mag -vs- 7mm Rem Mag

    Hi all,
    I'm thinking about getting either a .300 win. mag or a 7mm. rem mag as an all purpose gun for deer, bear, elk and perhaps some day moose. I want a gun that can shoot accurately out for distance. My regular deer hunting area gives me shooting opportunities out to 1000 yards. Most shots would be expected at 400 or less. I have been thinking about the .300 win. mag, but people have been saying to get the 7mm. mag. Suggestions?

    Never shoot a 300 mag, but my 7 mag has done everthing I ever asked it to. Zeroed in at 300. Taken deer with it beyond that. Would guess either would serve your purpose.

    Either will be fine, but shot placement is key. Let me assure you, you will not be taking shots past 400 yards. 300 yards is a long, long way. Unless you specifically set up for extra-long shots and practice your butt off, it is improbable you will hit any part of the deer. It is also not hunting at that distance, just killing. I 'know' a ton of people who 'routinely' get deer at 300+ yards, with zero hold-over, no wind drift compensation, etc. It is BS. Not that it can't be done, it just very seldom is.

    I have them both, and I won't part with either one. A lot has to do with the bullet that you are using. I use the 7MM for deer, but the 300 will carry a larger bullet better.

    1000 YARDS!!!! I refuse to comment.

    Wait, I think I just commented.

    Both are awesome calibers and grand fun but, of those two choices, I would take the 7mag. for performance, cost and comfort.

    There are people who are capable of taking shots at 400+ yards and taking game cleanly. If you have to ask for advice you are not one of them. For me I am very comfortable at 200 and would take a shot at up to 300 if conditions are right. Like Harry Callahan said, "A man has to know his limitations."

    I'm not planning on going out and shooting a deer at 1000 yards. I would like to have something that will let me reach as far as I am capable. I have recently started shooting my .223 alot. I have been shooting out to 400 yards off a bench, and am getting better. I plan to continue shooting my .223 alot to build my skills, but just want a hunting rifle that will hopefully meet my future skills.

    if you reload, 7mm can shoot a lot flatter than the 300. With the 7mm bullet selection would be key. at ranges up to 300 yards you will shoot through the broad side of any deey with little execption with either round. The 7mm is a bit more versital in that again with the right bullet you could varmit hunt with it too. You can buy 7mm mag every where but 300 mag seems a bit more scarce. all in all I would go 7mm mag, or might think of an ultra mag.

    Pros: Great deer gun, especially long range shots.
    Cons: I do not like this caliber for elk. I think it is ok for long shots, but when I hunt elk, most of my shots have been under 50 yards. I think the 7mm travels too fast and is too small (bullet) to do the proper damage (and provide shock) at those close ranges. My uncle lost a monster bull when he shot one at 20 yards through the lungs with his 7mm.

    Pros: Very versatile round. Can take about anything. Close or far.
    Cons: Ammo is not as cheap as say... the 30-06. Recoil is punishing for the gain you get over....say.. a 30-06. A few years ago I thought of getting a 300 Win Mag to replace my 30-06. Someone then recommended I take a good look at the ballistics...especially if I use Federal High Energy Loads. I was suprised. There really wasn't that big of a difference. I concluded that I could shoot high energy loads if I really want to reach out there (as if I had a .300 win mag) or I could shoot regular loads for most of my needs. I kept the 06 and saved my pocket book and shoulder.
    Sorry, sounds like I'm recommending a third option. :rolleyes: BUT if you must choose between 7mm and the .300, I would go for the .300 since you are also after game larger than deer.

    I find myself in the odd position of agreeing with Shawnee, for once.

    But it could be just because it's a smaller caliber. The 7mm will give you very close to .300 WM energy, with less recoil and flatter shots.

    175 gr (11.3 g) Soft Point @ 2,860 ft/s (870 m/s) 3,178 ft·lbf (4,309 J)


    .300's 180 grain @ 2960 fps for 3,502 ft·lbs.

    Really, I would think about how likely you are to use this for each type of game. If you anticipate primarily deer and elk, you might want to go for the 7mm. If you're thinking of taking on brown bear and moose, the .300's ability to throw a heavier bullet (200 grain @ 2700 fps) might be welcome, despite the significantly heavier recoil.

    Northslope, the 175 grain 7mm has good sectional density, which provides penetration with good bullet selection. Here are some heavy for caliber SD's for comparison:
    .264" (6.5mm) 160 grain, SD .328
    .284" (7mm) 175 grain, SD .310
    .308" (.30) 200 grain, SD .301
    .308" (.30) 220 grain, SD .331
    .321" (8mm) 220 grain, SD .301
    .338" (.338) 250 grain, SD .313
    .375" (.375) 300 grain, SD .305
    .416" (.416) 400 grain, SD .330
    .458" (.45) 500 grain, SD .341

    Take some aspirin and drink plenty of fluids. I'm sure you'll recover, probably.


    "My under lost a monster bull when he shot one at 20 yards through the lungs with his 7mm."

    I would respectfully submit that the real problem was the choice of shot placement - a better option being a placement that wrecked the mobility of the animal (ie. through the shoulders or a CNS shot).

    .300 WSM vs .243 Winnie Pooh

    My son wants a .300 WSM for deer-hunting, while I'm comfortable with my .243 Winchester. What Gives? Blasting away a mere whitetail does not require a cannon. You and I should both know this. His synopsis involves future hunts against gigantic Elk, etc. When I die, I hope he'll cherish my inherited .243 Winnie Pooh. I have no idea how to talk him out-of such massive over-kill he seems to have his heart set-on. If 2200 fps/lbs of muzzle force cannot subdue his quarry in the 21st Century, I didn't teach him to aim as well as I thought I had. Actually, he's twice as accurate as I am. So, why does he desire so potent a round? I'm confused and seemingly under-powered regarding a valid answer. Chances are currently that only Wolves will be left to shoot anyway. cliffy

    True. Lungs was not a perfect shot. Elk was running past him. He was over 80 yrs old at the time. But the bullet just shot right through. To be fair, I don't think he was shooting "premium" ammo. At ranges that close, I still prefer the .30 caliber bullets.

    the 7mm will do what the .300 will do, with a flatter trajectory and less recoil, but with slightly less energy. if you hunt bear a LOT, go with the .300. it may just save a limb, or even your life (lets hope it doesn't come to that...:p) if not, go with the 7mm.

    This comparison is easy....either will do a great job and more for what you want. This is a coin flip in my opinion. Just remember, when you shoot off a bench at the range- the target stays put. Part of what makes long-range shots at animals iffy is what the animal might do during the time the bullet is on the way. What was (or would have been) a perfectly placed shot at trigger squeeze time can become a tragic gut shot due to animal movement (plus all the regular variations in wind, elevation, range estimation, etc). Us bowhunters deal with this even within 20-25yds.

    Every animal I've double-lunged at 20yds (including a 6X6 bull elk) [I]with an arrow[I] went down....even w/o expanding, would've thought that a fatal shot...sure he got both lungs?[/I][/I]

    Some 7mm Don't have less energy!

    Some .30 calibers are, to date, over-rated powerwise. Some 7mm Magnums kick .30 caliber butt. Some 6.5mm rifles are totally awesome, mainly referring to the NEW Ruger Hawkeye .264 Winchester Magnum reincarnation. 140 grain 6.5mm fare is designed for 500 yard kills within the extreme prowess of a .264 Winchester Magnum! Sorry to downgrade this thread to upgrade to the flattest shooting, most potent caliber ever devised. What in America can this caliber NOT KILL cleanly? cliffy

    300 win mag -vs- 7mm Rem Mag

    Like everyone is saying they are pretty close. I had that delema 30 years ago and shot a Remington 7 mag and my uncles Winchester 300 mag. I did a lot of reading on both. For deer and elk. placement is formost. I settled on the 7 mag in a Remington. I has been my favorite reach way out there rifle. I also love target shooting with hand loads. I shoot a sierra 168 gr. boatail and with a rest can hit a quarter every time at 100-150 yards. PS. A good scope is necessary as are quality mounts. Chose your rifle practice and be confident with it and enjoy shooting it.

    A scope on a 7mm Remington MAGNUM

    What Power -X to use? How fast can it be dialed down, including objective adjustment, if necessary? 4.5-14x40mm for long range? Is a mere 3-9x40mm adequate? I'm lost in the power of it all. cliffy

    A scope on a 7mm Remington MAGNUM

    I use a 3x9 it has a bullet drop compensator I just dial in the range 100-500 yards. It has never failed me. Any one else have scope ideas??
