short mag

[yorketransport]

Rifle cartridges are just like engines, there's no replacement for cubic inches. The case capacities from my fired Winchester brand wsm cases average 81.4gr water. My fired Winchester brand 300 Win Mag cases hold 93.5gr water. When loaded to equal pressures using powders of the appropriate burn rate the full length mag will win every time. Remember that if both rifles have 24" barrels that the the wsm will have a greater usable barrel length because of the shorter chamber dimensions.

My experience with a handful of rifles chambered in both calibers backs this up. There is the "efficiency" argument but in my experience that's always been exaggerated.

The differences in ballistics between the 300 Win Mag and the 300 WSM are close enough that I wouldn’t choose one over the other based on that factor.

Action length, magazine capacity, availability of ammunition and components and other factors would play a greater role for me. There are advantages to each.

Both are wonderful cartridges, and in no way should one diminish the other. I have a slight preference for the WSM due primarily to the fact it is a shorter action.

 All of the WSM calibers are great and the difference of weight between the long action and the short action is enough for me.The ballistics between their big brothers and the WSMs are really negligible in the big picture. The 7wsm is , in my opinion one of the best calibers ever made. 
 Never could figure out why it didn't make it.

I never could understand why a 6.5wsm never became a factory round? Or even the 25wsm?

[Bigshooter]

One thing to remember about the wsm cartridges is it is true they are based off of the 404 jefferys and the cases are all the same same length but the 7mm's shoulder is slightly forward with a shorter neck than the rest of the wsm cartridges.  This was done because the 7mm wsm would chamber into the 270 wsm which we all know would not be good.  I always thought with this extra powder capacity even though it's not much would be the case that reloaders would flock to over the rest of the wsm family.

So what your saying is that very few 7wsm in circulation?

I think it's is the lest popular between the original 3.

 There really aren't, they can be difficult to come by, currently I would bet there are more custom 7WSM built than production models.

Another 7mm WSM hunter/shooter here.  I harvested my buck this year with mine using the factory 140 grain Supreme factory stuff.  Pretty impressed.  I have saved all my brass since 2006 or so but now it is time to find the elusive 7mm WSM reloading dies...

Between my current 300 wsm that's 7# scoped...a yet to be made 9 # LR 7 wsm and another yet to be made 358wsm @ 7#'s...a guy would have the perfect set up for everything in North America in my opinion

[bobcat]

Gee, I think you could do everything with the 300 WSM and skip the other two.

I like lighter faster calibers for game like antelope, and would prefer to use bigger bullets for brown bear and bison. However, if I could only own one caliber the 300 WSM would be at or near the top of my list.

[Buzz2401]

I love my kimber Montana in 325 WSM.  It performs right in between the 300wm and 338wm.  It weighs a skosh over 7lbs with a scope and doesn't kick even close to my last 338wm.  I do think it odd when guys buy 8-9lb rifles in the WSM.  They were designed for lighter rifles.

[bobcat]

I'd love to have an 8 pound 300 WSM with a 26 inch barrel set up for long range shooting. (Long range to me is 600 yards)

[kentrek]

Gee, I think you could do everything with the 300 WSM and skip the other two. 

Haha but where is the fun in that ! Currently I'm solid for deer and elk up to 700 yards....but a 7# scoped gun just doesn't make for easy long range shots(400-1000) so that's where a heavy 7 wsm would come in...then what happens if your like BLRman and have your main gun go down and have to resort to s back up ? No 243 for me....358 wsm would be just the ticket...no long range stuff needed just a good old fashion packable rifle with lots of wammy to it if I ever chase moose or grizzly bear

This way is much funner
