Was wondering how long it would take to molest that name...

Ingwe-so "A" has a 257 WSM reamer?

Dober

It does sound good, don't it? Need to get the Web-fu working and see what I can find for dies.

For some reason or another I kind of think that the 25 would be a bit more user friendly than my 338...

6.5 WSM has at times given a shout to my loony side as well.

Dober

[bleep] me running, every time I do some sort of 25WSM search I get the 'Did you mean 25 WSSM?' If I did mean that I would have typed it.

[bleep] that little super short piece of trash.

Don't ignore the .325 WSM. It has several advantages. To wit:

- explaining what the hell it is, and isn't, is always a great way to get your buddies eyes to glaze over;

- it makes finding bullets and brass more challenging, and challenge keeps the mind sharp, feet fleet, and pecker willing;

- it'll shoot an Accubond through a deer lengthwise. Starting at the rear shoulder no less. How slick is THAT?

- an 8mm jag works GREAT for tight-patching a .30 bore;

- uh.... I'm sure there's more, but that should be plenty.

Holy bat [bleep], even Lee makes 6.5 Wizzum dies

IMO, the move to go WSSM instead of WSM in a 25 was one of the all time biggest pooch screws ever!

A while back I had a rag around here with an article on the 25 WSM in it, if I could ever find it I'd scan and email to you if you wish. If, I can ever find it...

Thinking it might just be easier to do a 7 WSM and run 120's...

Dober

There's a thought!

Or a 270 and run 110gr TTSX's

That's another good thought, or a 300 and the 130 TSx's...

And then there's the 325, nope not gonna go there as this will quickly go into the toidy...

...........I did own a Weatherby Vanguard chambered in the 300 Win Mag for 34 years and have nothing but great things to say about that cartridge. Two and half years ago, I converted over to a new rifle in the 300 WSM, because I preferred the rifle chambered for it.

As my Lyman manual says about the 300 WSM (para-phrasing)..."The 300 WSM averages 30 to 50 fps below the 300 Win, while using 8% to 10% less powder."....... Both the 300 Win and the 300 WSM were tested with 24" barrels in the Lyman manual. Performance wise and on any game hunted with either 300, there is absolutely no real advantage that one would have over the other in the field given the same barrel lengths. The 300 WSM is much closer in ballistic performance to the 300 Win, than is the 30-06 to the 300 WSM.

On the other hand and given the same barrel lengths, the 270 WSM exceeds the 270 Win by around 200 fps. The 270 WSM is closer to the 270 Wby than is the 270 Win to the 270 WSM. So to answer your question; yes, the 270 WSM does stretch out the 270 Win while approaching the 270 Wby. Imo, if you`re not successful and can`t kill the game with a 270 WSM given the same distances, you won`t be successful and kill the game with a 270 Wby either. They are close enough imo, to make that determination.

In considering the 270 WSM or the 300 WSM, the 270 WSM would be a slightly flatter shooter, while the 300 WSM will deliver better downrange energies with heavier bullets. With maybe the exception of the dangerous bears, whatever you can hunt with one, you`ll be able to hunt with the other.

Good post;Sqeeze is right.

How much velocity any of these cartridges give over the other depends entirely on how hard you're willing to run them.I've toyed with 3 270 WSM's and the factory 130 gr stuff gave a shade under 3300 fps with factory 130 gr loads.With handloads,and RL22,I stopped at 3225-3250.The rifles were a pair of M70 FW's and a Kimber Montana.

OTOH,a custom 270 Weatherby I had built with a 25" Lilja gave over 3400 with the 130 gr Weatherby factory ammo.My handloads operated at about 3350.

I don't own any of these any more mostly because none of them did anything I couldn't get done with a 7 RM and equal bullets.Actually you can take the 270WSM,7mmWSM,7RM,270 and 7mmWeatherby and drop them all in the same hat;there is no difference between them in drop,energy at close and long range,and performance on game.All will go faster than a 270 Winchester because they hold more powder.

Any of them will shade a 270 Winchester in trajectory to 400-500 yards by about 4-6 inches.If your rifle is not accurate,you may not see a difference at all.

The 300 WSM's I've played with (3 Model 70's and a Kimber Classic)were so close to the 300H&H that it was hard to tell the difference.Using RL22,both gave about 3150 with a 165 gr bullet,and right at 3000 with a 180(or so close you could not tell the difference).What one will do the other will do.

WSM brass is pretty tough stuff,and the factories load them to pretty high pressures.

Dober...the Big A should have a 25WSM reamer, I will reconfirm when next I see him, and one or the other of us can pass the info to Steelhead if he is interested...

C`mon! Get it right!!!!!!!!!!!!!!...........LOL! LOL!

Yeah Dober..checked it out today...hes got the reamer....and I talked to the dude down the street, whom he built a 25 WSM for...
Shoots a 26" Bbl...110 Gr. Accubomb @3360 fps..
Excellent accuracy...RL22 or RL25
Makes brass out of .270 WSM, one step...no neck turning

FYI

Ingwe

How does that compare with the Roy?

Funny you should ask that question, cause the guy I was talking to was a real gun crank, called around for load data and got this from Sierra; Case Capacity/Water weight is exactly what the 257 Roy is, so work up data accordingly...speed/ bullet weight ratio is also so close it doesn't matter...so it would appear if you want a short wildcat.the 25 WSM might work for you...if you are more a traditionalist...the Roy...
