Home Forums Hunting & Shooting Ask The Gunwriters 300 Win Mag vs 300 Weatherby? What are the differences for big game hunting?

I own a fairly light model 70, #2 contour, Edge stocked 300 Win. Mag. with 24" barrel. I get the 168gr TSX to shoot about 3200fps.

I mainly hunt moose, sheep, goats, black bear, with some elk and deer in lower 48. I also hunt in areas that have brown bear and/or grizzlies at times.

I was thinking of a 300 Weatherby for a change and wondered if it was really ballistically worth it or if it's more for nostalgia?

I want a rifle all-up at 7.5 lbs or less; I would stay with a 24" barrel. Also for multi-purpose hunts.

What trajectory differences would there be between those cartridges? Any experience to share?

counterproductive, you give up a great design to get rounded shoulders and a couple more grains in the case.
Stay with the 300WM

Given what you have the potential difference would be a waste of time.

I have a pair of Roys and 3200 with a 180 is no sweat in either of them. You have to decide if the little extra is worth it. I doubt any critters would notice a difference.

You leave out the Weatherby Mk V ultralight if you want a 7.5# full-up rifle, I suspect mine is 8+ ready to hunt.

W/O the added 2" of barrel, I believe you would be wasting time and $ for brass bumping up to the Wby round.

Nope ain't worth it...Keep it a Win mag.

IME there's 100 fps diff tween the two. I'd stay with the Winnie the Pooh.

And just so you know the rifle you describe sounds absolutely wonderful!

Had quite afew of both.If you had a 300 Weatherby,I'd say"keep it"...if you had a 300 Win Mag,I'd say "keep it".

Yes you can make a 300 Weatherby go faster with a 180,about what you get with a 165...in the end it does not matter;they're both great rounds.

I all but retired my West German 300 Roy.Darn Winny with the gain twist tube exceeds it with lighter weight bullets.It's only feet difference in 180 or 200 grain bullets.

Seems to me when a 30 cal 180 reaches 3K it's all good no matter the brass cylinder fueling the bullet. Anything beyond that is fuel for the tiny gray cells only...

Mike: It'e the freebore and larger capacity of the Weatherby; it does better with heavy bullets.In working up loads I noticed I could not get much more speed with the 165 than I could with the 180......course if you want to load to Weatherby factory pressures, different story...

The last batch of 165 BT's in Weatherby factory ammo that I chronographed did 3430 from a 26" 300 Weatherby M70 barrel.

I agree with everything that's been said so far, partly because I am such an agreeable guy (right!). But also note that I am a .300 magnum slut, so have a .300 WSM, .300 H&H, .300 Winchester and .300 Weatherby....

But if limited to one, would probably choose the .300 Win.

Well, maybe the .300 H&H.

It would depend on how practical I felt at that moment.

Obviously you missed the part about it having a 24" barrel, not a 23"

Wow thats moving Bob.Forget what my 300 Win Reloader 22 165gr NP numbers are but she ain't cruising that fast.

Should add my Weatherby has a 24 inch tube from factory.Wish it was a 26 myself.

Too funny Powerguy-the last time I had a 300 tube on my 700 it was a 23" Krieger. First I had it in Winnie the Pooh and then I had it rechambered to the Bee.

Great elk Mark, congrats


Sorry for the hijack

I have owned a few 300 win mags, a 300 weatherby, 300 rum and a 300 shorty.
Given one rifle to do it all in NA and everything in Africa short of buffalo, ele and rhino I would build a 300 RUM with the following blue print.
My rum is a model 70 mag action, 24" mike rock #3 barrel, Talleys lightweight mounts,Williams bottom metal, Jewell trigger, Leupy 3.5-10x40, Echols Legend/Edge stock. All up, short ammo it runs a hair under 8lbs. I wouldn't want to go much lighter with any 30 cal mag. It also spits out 180 gr bullets around 3300 fps give or take with loads under max. You may or may not get that out of a 26" tubed Weatherby but you still will have to deal with expensive brass, a belted case, and the down sides to running high pressure loads.

Oh man, is that a Panzer? Looks to have a significant carbon footprint!

Yes it is.Tiger Panzer MK VI.

Brad: Geez...sounds to me like a 300H&H...or it's rotund, vertically-challenged contemporary....



Mike: Yes a 300 Weatherby,all-up,will pack the mail!
