300 wsm or 7mm mag

I am looking to get another long range gun for hunting in North America- mainly Deer and Elk. Give me some opinions. I am thinking the 7mm has superior ballistics across the charts.

Re: 300 wsm or 7mm mag

I own both, and there both fantastic. Depending on the terms of long range they both have there advantages. Depending if your going custom, reloading, and your experience. My guns are both factory but shoot extremely well. My 7mm is holding around .75" at 100 yards right now, and my 300. wsm is holding around 1" at 100 yards. I dont hunt extreme long range, but would be more then happy squeezing the trigger at anything within 500 yards. I bought the 300. wsm for black bear, and moose and the was given to me from an uncle.

Re: 300 wsm or 7mm mag

nond4v8,

This always turns into a 30 cal vs 7mm thread. Ive started them and researched it till I couldn't retain any more information. Ive always been a 30 cal guy and still hunt with them, but my long range gun is a 7mm Mag. Based on the criteria that I established, ( 1000 lbs of energy on impact and still supersonic, with no muzzle brake) the opinions I got here, and the research that I did, led me to the 7mm choice hands down.

** Im not trashing the 30 cal here guys, or arguing the effectiveness of putting meat in the freezer, just my train of thought on my recent purchase.

Here's some of my reasoning:

1. Recoil -- to push a 30 cal bullet at the initial velocity needed to meet my criteria, I feel would have produced a rifle that was not "fun" to shoot, and therefore my level of proficiency would suffer due to not shooting as much. I dont want to have to use hearing pro in the field, so the muzzlebrake was out for me.

Energy/ velocity -- Run the numbers on a .284 168 Berger out of the 7 mag, and will retain more energy and velocity than the .308 180 Berger from a 300 win. ( I know the 300 Ultra and 30-378 will get them there, but remember my muzzle brake criteria?)

I guess the deciding question is how long of a shot are you wanting to take? If its past 700, i say go with the 7, otherwise, the 30 cal has served me well thus far out to 500.

Goodluck and let us know what you decide.

It seems that the 7mm bullets have a higher BC and they have greater velocities meaning better results at longer distances. You can get BC's over .600 from a couple of different companies. With the .308 you have to go over 200gr to get anything comparable, then the velocities and energy will suffer as they get further out because of the heavy bullet, not to mention the recoil of the magnum.

Re: 300 wsm or 7mm mag

I just got a 300wsm, there's seems to be alot of ammo out fo it. I'm getting just ove 1/2 groups at 100 from a factory browning x bolt.Both will kill the same things. I do like the gun in a box bline or walking better short, light, accurate and packs one heck of a hit for that short fat litlle shell.

That's probably because any scope that would be good for one would be work ok for the other. Personally I MUCH favor the 7mm Mag over the 300 WSM. It's not because of the cartridge. It's because nearly all gun manufacturers keep putting the WSM cartridges in short actions so you can't shoot low drag bullets. At least some companies like Remington and SAKO put the 7mm Rem Mag in rifles with 3.6" magazines so it can shoot low drag bullets. In my opinion both the SAUM and WSM series rifles should have at least 3.4" magazines, not the piddly 2.825" SAAMI spec magazine if they're to be used for long range shooting.

I don't own any WSM rifle for that reason. I do own a 300 SAUM in the form of a DPMS LR-30S but the short magazine really cramps it's performance.
