300 winmag vs 7mm mag

I am wanting to build a long range hunting rifle and was wondering what cal. would be the best to use, I will be hunting deer and elk size game with this rifle and I would rather stay with standard load instead of a wild cat due to my limited hand loading experience. So tell me what you think

Re: 300 winmag vs 7mm mag

I've shot thousands of rounds from 7mm Rem Mags and it is one of my favorite loadings. I've taken dozens of deer and several elk with it. However, the larger caliber the better when talking about Elk (.338 is even better). I'd choose the 300WM if I had to choose between it and the 7mm RM though.

For a long range round, the Rem Ultra Mag would be even better (300RUM is a smokin Long Range rig). If it was Elk only, I'd say the 338RUM instead, but the 300RUM is an awesome factory round.

The 300WM is a great round and has great over the counter ammo available, it doesn't shoot as flat as the 7mm RM. I setup a Weatherby MarkV in 300WM that shot factory ammo at well under 1moa. It's my dads rifle and I'd borrow it in a heartbeat for deer or elk if I didn't have access to my own rifles.

Either one will do what you want, but consider the 300RUM as well.

If some is good and more is better, then too much is just right.

Re: 300 winmag vs 7mm mag

I used to hunt with a 7mm RM. Now I have a 300 WSM and 300 RUM (and a 7RM).

So first, I would recommend the 7 WSM or the 300 WSM over the RM & WM.

The 300 WM will shoot a 180 gr bullet about as well a 7RM will shoot a 160 bullet. Their trajectory and rang will be very similar with the 300 delivering a little more payload on target. For elk size critters, I would recommend a 30 cal bullet or more, but a well placed shot with a good performing 7mm bullet will do the job. With either cartridge you are looking at about 900 yds hunting range, give or take, with most loads, IMO.

Hope this helps,

Its a toss up,either will do the job,I shoot 7mags and the accuracy is outstanding,my 8 mag shines past 600 with a heavier bullet.There are always .284 bullets on the shelves here when the .30 section is empty,.

300 win mag all the way, over the counter ammo is common and cheap and it makes more kinetic energy than 7 mm mag.

Another vote for the .300 Win Mag!

338 Lapua
Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.
