Long range elk/deer... 7mm mag vs. 300 win mag?

I'm looking to get a new hunting rifle to replace the one that was stolen a few months back.

What are the differences between the 7mm mag and the 300 win mag? All I've really heard is that the 300 kicks harder. Does someone know where a chart is that shows velocity and energy at different distances.

Thanks,
Clint

I know that the 300 recoils about 32 ft lbs shooting a 180gr bullet at 3050fps. The 7mm recoils probably about
26 to 28 ft lbs shooting a 160 gr bullet at 3000 fps. I shoot them both and can't complain about the recoil because it doesn't bother me.

Re: Long range elk/deer... 7mm mag vs. 300 win mag?

Clint,
Heres the basic rundown...
If you are planning on loading heavy for caliber bullets, with both cases near their max capability velocity wise, in a rifle that will be the same weight for either case, recoil will be nearly identical. I doubt anybody but the most recoil sensative could tell the differance.

I know I can't, especially in a heavier rifle like moat of us shoot at LR.

The strength of the 7mm lies in its exterior ballistics. 168-180gr bullets with their high BC require few moa at LR, and buck the wind quite well. Better than anthing you can throw from the 300WM in fact.
The strength of the 30 lies in its terminal ballistics 190-220gr bullets retain high velocity at LR and land with authority. Noticabely more authority than lesser bullets.
Now then, just how much differance is there? really not a lot. There are folks here who have killed elk at LR with the bigger 7mms, so they obviously do ok, and there have been thousands taken with the 300WM, so they do ok as well. The differance in trajectory is there, but unless you are planning to shoot at 1200+yds, the differance is not pronounced. at 1K the 220SMK from a 300WM will drift 1" per mph more than the 180 Berger from the 7mag. trajectory wise at 1200, there is only 5 moa differance, virtually meaningless. Energy wise, the 300 wins to 900 or so, and the 7mm past that.

Right now, my 300WM is great. Its killed p dogs past 1k, and paper at 9/10 of a mile. Ive shot enough stuff between 1350 and 1575 do decide that id have no problem with killing power at 1500 if I can get the bullet in the right place.

That being said, a 7stw reamer lays on the desk nest to the computer mouse, and where 220SMKs have flown, 180Bergers and 176 Cauteruccios will fly soon.

Wow. Thanks guys. Very informative. So basically the 7mm works better than the 300win in wind and has a flatter trajectory, but the 300win is more powerfull and a longer range round yet kicks a bit more?

Both the 7 mag and 300 mag have a place in history and should be put up on the wall next to the 30-30. The word mag was an old selling point. Now it's Ultra Mag or Short Mag that you should look at. In comercial rounds the 7mm STW is hard to beat.

I still maintain the 300WM is the best round for a new LR shooter, if only for the fact that its easy to load for, good loads are well known, and you can buy factory match ammo.

I agree. I've got a 7mag and I sold my 300WM but bumped up to the 300 RUM.

But, the 300WM is certainly hard to beat.
