Thread: 300 win mag or the 7mm rem mag

    Question 300 win mag or the 7mm rem mag

    Trying to decide witch gun is better, looking to buy a new gun

  2. #2


    I own a 300 MAG WIN. Powerful and reliable rifle. I have not shot the 7mm, but i have heard that they are lighter and more accurate.

    I am considering retiring the 300 for a lighter, faster bullet pusher like the 264 or 270.

    Depends though on what you are using it for. I strictly hunt deer with mine.

    Like Jack said, what are you using it for? The 7mm is big enough except for perhaps brown bear. It would be fine on elk, but I would think about limiting how far I shot at an elk with it (300 yards or less).

    Do you intend to take really long shots (300 yards +)? If so, and you have the ability to do that, then you may be better off with the 300 if the targets are huge animals. For large deer and smaller, the 7mm should be fine for any distance you're capable of shooting.

    The 300 will recoil more, so consider that. Also consider handloading so you don't have to take a recoil and noise beating every time you shoot it. You can turn the 7mm Mag into a 7mm mauser or a 300 Win Mag into a 308 ballistically and reserve the top end loads for long range or huge animals. Both calibers have a huge selection of bullet choices. There are probably the two calibers with the most choices.

    Default Many choices...

    A few big questions - some of which have been asked already.

    What are you hunting? What is your physical stature and how prone are you to developing a flinch?

    I shoot a .280 Remington and .32 Win special (for bush hunting) personally, and use a 30-06 and 300 Win mag for my work firearms. My .280 or the 30-06 work for moose, elk and deer, and at work the .300 is for larger Bison. I'm 5' 10" and 200 lbs. and the .300 carries a good punch - my shoulder is about done after 10 rounds whereas I can shoot 50+ rounds out of a non-magnum without pain.

    If you are batted around by a large calibre you are less likely to shoot accurately and a heart/lung shot with a .308, 30-06 or .270 is worth more than a wild round from any belted magnum. Those are my thoughts. Good luck.

    Default 7mm or 300

    Hi Krusty, The main question is what are you hunting with it. I have had a 7 Mag since about 1975 and it has done everything I have needed. I have shot 6 elk in Arizona and Montana. Longest shot was just under 300 yds. I have shot many antelope in Montana and longest is just over 400 yds. ( I practice at long ranges) The recoil is not noticeable to me when hunting, but I do 'feel' in from the bench. I use a recoil shield on my shoulder from the bench. The new premium bullets available are suitable for ALMOST everything. I would look at the 300 SHORT MAG if you are going to hunt big nasty critters like bears, or possible hunt elk, caribou, deer, in bear country. My good friend has a 300 Win Short Mag and loves it. You WILL notice the recoil on this caliber. The 300 ballistics are also great.

    Depends on what you want to use it for. Both guns are pretty heavy and can be a load to haul with you up and down the mountains. The 7mm mag has stellar accuracy at distances and the .300 has more knockdown power. That being said -- how much knock-down power do you need? Unless you are going after a cape buffalo or an Alaskan Brown, the 300 mag may be too much gun. Of course, for most large-game applications, so is the 7mm.

    I have for years used a .270 for deer and antelope and my 30-06 for elk and moose.

    I perfer the 7mm mag do to the flatter shooting but there are more bullet choices for the 300 win. I'm not a big fan of belted bullets. But like everyone has said, it all depens on what your shooting at. Both would be able to take care of most of the big game in the US other than say a large brown. If I was to choose between the 2, I would go with the 7mm.

    Default 7mm has little gain

    costs more to shoot and doesn't have much more reach than a 270win or 280rem. if you need power, go with the 300winmag. But, consider if you really need it. the 30.06 will do what the 300 will do within reasonable hunting distances. for unreasonable long shots for that once in a lifetime buck, the 300 has the OOMPH to ventilate way out there. but at a cost. I'd stay away from the SHORT MAGs for now. they offer nothing that isn't available, and usually cost more. If your experience level is where you still need to ask, then I always recommend starting at the tried and true. Go 30.06 if you are getting only one gun and moose/elk is on the menu. go with 270/280/308 if only going for deer sized game. You can get ammo anywhere, and it'll not break your bank account.

    Now.. if you handload, have more than one gun, or live near a major ammo supply, then.... well that's for another thread.

    Default 7mm

    I own a 7mm savage its a a good all around calabar,,,from a ground hog@2000 yards to a large black bear,,,i own several other rifles,but the 7mm does the trick,,,i do a lot of reloading and i created a wildcat load,,7mm rem mag with a 65 grain bullet great for open flat shots like groundhogs,,

    Both guns are under powered. I wouldnt shoot anything bigger than a groundhog with either cartridge. If you're hunting white tails try the 458 win mag.
