I already have a push feed 3.6" capable 300 wm. I like the ew because it's stainless, crf (and ease of bold disassembly) and has a decent stock. I'm not aware of a 3.6" crf stainless b&c type stocked rifle for the price of a gently used FN m70. What else is out there?

I shot both EWs back to back and they weighed within an oz of each other since the 300 wm had alloy mounts and the 300 wsm had steel rings and bases and since the 150gr ttsx shot virtually the same speed I noticed no difference in recoil. The recoil argument has no sway in my decision.

No, Weatherby Mark V for 300 wby mag, Winchester model 70 Winlite 300 win mag and for the 300 wsm Browning Abolt, MOdel 70 SS Classic,Sako 75 SM and a Weatherby vanguard .

I've had 7 300 WSM's since the cartridge first appeared around 2002... my current is a first year production EW that is among the most accurate factory rifles I've ever owned. 180's at 3,030 - 3,060 fps with RL17. I may drop it in a Banser to get it under 8lbs all-up.

300 WSM ammo is a snap to find around here, and I really haven't seen it's more than 300 WM, but I don't shoot factory ammo so maybe don't pay close enough attention. Brass is also widely available, especially now that Hornady is making it. Seems a simple matter to stock up 250 pieces which should last the life of the barrel. The 300 WSM has become a "world cartridge."

First off ! I have NOTHING against the WSM.

WAY back there the W M always appealed to me. IIRC I have my 5 th W M and have had NO complaints with the cartridge. My second one was a B B R that had some problem that Browning Utah could not fix. After it returned from Morgan Ut and still would not group my dealer swapped a Rem 700 BDL to me. The first group I shot with the 700 went 3/4" with 4 shots.

I've been satisfied with the 300 WM so that I saw no need to try the WSM. I like the 6mm Rem case better than the 243, and the 270 W case better than the 7-08 AND the 300 WM better than the WSM. I like long and slender better than short and fat.

We all have our personal preferences.

I prefer the .300 Win Mag to the 300 WSM as well. I have a Remington 700 Alaskan Ti chambered in 300 WSM that I'm going to sell or possibly convert to .375 SAM for my gf. I also have a Kimber 8400 300 WSM that currently has a 6.5 PRC barrel screwed on. I have no plans to sell or convert the .300 Win Mag rifles that I have.

Might be just my experience but WSM's and Remington 700's just don't feed as smooth as other brands. I had a Sako SM action that fed WSM's so smooth you could not tell a cartridge was fed and the Weatherby Vanguard was not far behind. If I had a 300 win mag I favored and shot well I would not go out and buy a WSM.

The worst feeding WSM’s I’ve seen are M700’s...

Oh yea without a doubt

That’s because the 700 short action is really too short for the WSM cartridge. Like a 257 Roberts or 6mm Remington it is really more suited for an intermediate action

I agree with this. One thing that needs to be added, is you tend to get more loadings from the WSM brass too.

I like the 300wsm. Woukd take it over a 300 win mag. If I want more power I just step up to the 300 ultra.
With a 300 wsm you get a modern beltless case that has factory ammo loaded to its potential. 300 win mag factory ammo is always down loaded to less than wsm velocities.

I would go with the rifle you like best and the one that YOU shoot the best. All the .300 magnums are within a gnat’s whisker of each other in performance on game at reasonable ranges. I just cut to the chase with a .300 Weatherby and don’t worry about the trivia in the rear view mirror. Nothing bigger than the .300 Roy offers much improvement. Happy Trails

I had two 300 bees as well as a 300 ultra and a 30-378. I can get 3k with a 200gr partition and Norma brass in a 300 win mag and 3.6 magazine. I don't need more than that from a 30 cal.

The 300 wm at saami and the 300 wsm EWs would do all I need from a light hunting rifle. I would probably shoot the 165/168 ttsx in either and call it good.

Not to argue but I don’t have any problem with case life in my 300 WMs.
I would like to see test results comparing the two.

Jerry

My shoulder objects more to 165's loaded max than 180's at max... I find the 165's have a much sharper recoil.

I agree. I'm on seven firings for some belted magnum cases without any issues. It's not hard to get good case life out of belted magnums. Minimal resizing coupled with annealing as needed is all it takes. I find bolt lift easier for the .300 Win Mag and .375 H&H Mag cartridges compared to the 300 WSM. That's another plus for the Win Mag over the WSM.

Uh oh. I feel a lecture by Savage99 coming on....

s t - I deleted your comment so he would not see it.

As to short case life, improper, aka OVER, sizing cases causes excess headspace, albeit artificial, and therefore short case life. I remember the first couple of times I read “incipient” case separation I had no idea what it meant. Had to look it up.

The very first time I encountered it was in a military 303 British. I don’t remember what the rifle was but
the 303 is NOT a belted cartridge. Case separation can be created in ANY cartridge.

Jerry

I have loaded for both cartridges and I have experienced zero difference in case life...It seems a .300 Win does feed smoother in the rifles I have had but I'd still opt for shorter/lighter .300 short mag .....Hb
