.300 win mag -vs- 7mm Rem Mag

[KI.W.]

Never ever old-fashioned rimmed cases!

I personally use the 300, my brother uses the 7mm, both work out to 400yds. If you hand load you can get the 180 in the 300 going over 3100fps, has great power.

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

If he lost the elk how do you know it was a double lung, and not six inches farther back in the guts?

I personally prefer 7mm cartridges.
Think a 7mm STW.

If you are considering reloading, take a look at the available bullets in both calibers. I went with the .300 for the vast variety from so many different manufactures.

Both can be used, when reloaded properly, for many uses.

I have owned both. I still have my 7mm. For me, while hunting game in North America, I find that with appropriate bullet selection, both will do the job and then some. Personally, I find most high powered .30caliber chamberings give off excessive recoil and muzzle blast for what they actually do. I also like the better trajectory and better SD of 7mm bullets. My $0.02

My dad and I went through this back in 1969. Dad built a 300WinMag and I built a 7mmRemMag. We went elk hunting and both killed elk. As for deer hunting, the 7mmRemMag got used a whole lot more. A 300 is a lot of gun for deer hunting. If your rifle is used mostly for game bigger than deer, go with the 300. If not, go with the 7mm.

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

Sorry, but I'm gonna have to call BS on this one. You may even think it happened, but I will guarantee it did not. There is no animal on the planet that will survive a double lung shot from a 7mag at 20 yards...none. A few may live long enough to kill you, but even they will die shortly after you.
And let's suspend reality for a second and say that your story was actually true. How would having a 300mag have made a difference? an extra 100-200 fps velocity?, an extra 20 grains of bullet weight? A bullet diameter difference of .024"(24 hundredths of an inch)?
Now a poorly placed shot that did not hit the lungs at all, that is another matter entirely.

I have had both in Rugar #1 rifles and kept the .300 because of the greater choices of bullet weights.

In my opinion, the key to the retirement system is 180 grains at 3,000 fps or above. Difficult for the 7mm Rem Mag

Try a 300 Weatherby Mag. The 300 Win Mag is a compromise of sorts, case volume too small and neck too short, not sure if it was to stay withing a rifle size constraint or the production equipment. - You should get up to 200 fps more with better accuracy.
You WILL RELOAD. Even Walmart charges $40 for 20 rounds, although once you buy the brass the cost difference in reloads between it and the Win Mag is negligible.
With a 220 gr, bullet it'll take down any N. American animal, fast, and the lighter bullets/lower loads are fine for deer.
Best of all I got a Weatherby Vanguard in 300 Wby for well under $400 at Walmart.
