Home Forums Hunting & Shooting Hunting Rifles Practically speaking is there anything a 300 WBY Mag can do that a 7 Rem Mag can't?

The 270 and the 7mm mag are not in the same category.

I find that response somewhat surprising because it seems the 270 and 7 mag are much closer in comparison than a 7 mag and a 300 weatherby mag?

I don't own a magnum of any caliber but if I ever do I don't consider 10 grains of bullet and 100 fps to be not in the same catagory or a categorical step up.

The only magic thing about the 7 mag is that it comes in 7mm and that 7mm number is a very good number to have if one is interested in long range pursuits.

My personal 7 mm preference would be the 7mm Mashburn and though I don't have one I've followed a fella that goes by the name BobinNH threads very closely.

Bobins words on the Mashburn truely have me intrigued and I am very close to taking a step up to a cartrage that truely is in an entirely different catagory than the venerable 270.

7 Mag can match the .300 Bee in Warp speed Barnes (120 vs. 130).... and it can match it in external ballistics (.620+ BC at 3k). It does it with WAY less powder and recoil. It gives up some horsepower.... but it's far easier to keep on the road.

The .270 can almost match the 7 mag in warp speed Barnes.... (110 vs 120)..... but can't even sniff a 160 grain, .550-.650 BC bullet at 3000-3100 fps...

The only thing .30's do better than 7's.... is recoil.

ds -

Not quite. the 7s can't shoot 200-220 in the same category and some not at all.

Try to find a 200 NP in 7mm.

Try to find a 220 in 7mm.

My 300 wby shoots the 130 TTSX at 3714fps average. My 7mm rm never got past 3400fps with the 120s. How are you matching the 300 for warpspeed?

External.... not Terminal.... hence the horsepower reference. Pretty sure a 175-180 7mm pill would be awful hard to stop though... and a critter would be hard pressed to know the difference between .30/220 and .284/180...

Try to find a chick that'll shoot a .300 Bee more than once.... I've had a dozen ladies run the 7 Mag with 162s.... hence the keeping said horsepower on the road reference.

At 26"-28", a foot and a half of freebore, and 75k psi... visa vis Weatherby GangNam Style... and a 7 Rem will easily go 3600 with 120s...

With the new high BC 270 bullets one is very close to classifying the 270 and 7 mag with your same classification of the 7 mag and 30s.

The only thing 30s do better than 7s is recoil.

The only thing 7s do better than 270s is recoil.

With some of the new 270 bullets available it is sniffing at the door of the 7 mag to the tune of 20 to 30% less recoil.

If I decide to get into long range hunting and I am considering it I will be going a different route than the 7 mag for a number of reasons. The first reason is I've already dabbled in long range pursuits with a Custom 280 AI and though the 7 mag does offer more IMO it doesn't offer enouph more to warrant getting one over the 280 AI.

In retrospect I've found myself wishing I'd paid more attention to Bobins words on the Mashburn. It offers a realistic 300 fps over a 270 while at the same time has properties that seem to lend itself to easily attained low ES numbers. Something that I believe the 7 mag is not noted for giving up as easily

Check the Barnes manual. No voodoo in getting 3700 with the 130 from a 26" barrel. Their loads are almost 3700 with 24" barrels. 7mm on the other hand doesn't make 3400fps according to Barnes. If your getting 3600fps its not me using voodoo to get my speeds.

Voodoo is simply how you do what you do....

I've seen 3600 outta 120 NBTs and TSX, in a handful of 7s... Rem and Bee. If you have a number in mind, you'll find a way to get there.

Shod....

We've already seen the High BCs of these new .270 bullets be debunked... and the truth is more like .475 tops if you've got a 1:10". That still ain't shabby... and the difference is what it is. I'm with you in the 7s that are a step down from the Rem/Bee.... .284ish is a nice place to be.

If I need bigger than a .243/.260, I'm going to a Seven of some ilk. If I'm going bigger than that.... it's all the way to .375.

No.

Extra points awarded for brevity.

gee.....thanks.

Reader's Digest version for the attention deficit victims....It isn't a hard question.

The .270 and 7mm are the Weatherby chamberings that interest me. My tastes in .300 top out with the WSM. By your own statement you have not needed it.

If it were mine I would sell it and use the money toward a hunting trip.

I left my 7 in the safe the last 2 years to carry the 300 Weatherby. It shoots just about as well as the 7 but my 7 got about 3050 FPS with 150's and the 300 gets close to 3200 FPS with a 180 grain bullet.

The extra oomph at 3 or 400 yards is nice to have if you hunt close to the public private boundary. Recoil is grater but manageable - it hammers steel targets at 700 yards so I'm happy with the accuracy. If it fails to impress it will take it's turn in the safe but I love carrying a beat up vanguard that doesn't make me wince with new scratches and nicks.

Only owned 1 300 WM and liked it. Only 7mm is my current 7-08 that I'm waiting on components for.

That said - I suspect that the difference between the two is similar to what I found about the step from 30-06 to 300wm.

If I need to move up, 300 wm isn't really enough. If the -06 REALLY isn't enough, I'm probably in 338/375 territory.

I can't imagine a place where the 7mm isn't enough but the 300 is - terminal wise. There might be reasons why you'd want one over the other (162 AMax being one of them) but I doubt it's critical.

Using the phrase "practically speaking" in a rifle discussion is akin to using "fat-free" in a bratwurst discussion.

I thought a lot of the 7 mag until I bought a chronograph. On paper 160's at 3000 fps looks good. Most factory loads were just over 2900 fps and I had to really push the envelope to actually get 3000 fps with hand loads from a 24" barrel, then accuracy wasn't acceptable. About 2950 was as fast as I could push 160's and still get acceptable accuracy.

On the other hand I can easily get 3000-3050 fps with 150's from my 22" 30-06 and 2900+ a bit with 165's with very good accuracy. I found it pretty easy to reach 3000 fps with 180's from a 300 WSM with very little more recoil than 7 mag.

Never owned a 270, but 2950fps is not unreasonable with 150's. I just don't see 7 mag as being that much better.

To be honest the 300 WBY is more gun than I'd want, but 7 mag doesn't impress me either. I'd sell both and get a 270, 280, 30-06, or at most a 300 WSM.

methinks you are basing your conclusions on the results from one 7Mag...bad idea
