Questions about the WSM?
 

Right now I am currently looking into getting a new rifle which will be a Winchester Model 70 featherweight and want to get it in a short action. The WSM have caught my attention but this cartridge is a new cartridge to me. Is this a dieing cartridge like the WSSM or one that is here to stay? Preferable the 300 WSM and 270 WSM (Can't decide which one I want). Anyone that uses the WSM is there plenty of reloading data for it? Asking because I plan on getting into reloading in the next year or two. If these seem ignorant questions my apologies in advance just don't want to purchase a caliber 10 years down the road I can't find ammo nor brass to reload it with.

the .300wsm I believe is here to stay, and probably the .270wsm too.

Personally I'd get the .300wsm, more options IMO.
if you want something fast and flat like the .270 loads, then shoot 150grs from the .300wsm,
If you need more weight shoot 165-180-200grs

also with shorter barrels I think the .300 can do more from a shorter barrel than a .270, similar to a .308 needing less barrel than a .243....to reach full potential of the cartridge.

Have considered the same 2 cartridges and have decided I need a .300wsm.

What are you wanting to do with the rifle?

The 300 wsm and 270 wsm will be here for a while, the 7mm isn't as popular but brass and ammo is still available. A couple hundred pieces of brass will last the lifetime of a barrel or two.

Eventually I will use it on elk, mule deer, pronghorn once I move out west. I wan't a lighter rifle for carrying around and the flat trajectory of the cartridges appeal to me too. I was looking at it and have never heard much about a WSM. Really just an excuse to buy another rifle and try and use a cartridge I have never used before. I know they all kill just as dead as any of the other ones out there. Just figuring if purchasing a WSM would be a waste of money.

Nothing wrong with wanting a new gun, any WSM is a winner in my book. Check out Midway USA or ammoseek.com and look at what ammo they have in stock for any cartridge you're thinking about...if nothing is in stock at either of those two then chances are no one else will have it either.

I do not think the WSM family does anything better than more established cartridges. However, I do think that the 300 WSM cases will be available for loaders in the future.

You haven't said what you currently own. I had a 270 win and found it to be effective on both deer and pronghorn. The WSM version adds a little extra to the caliber. But being that you say elk is on the agenda then I would definitely opt for the 300 WSM. I have a friend that has taken 15 of his 28 Grand Slam trophies with a 300 WSM in a Win 70. That rifle obviously has been all over the continent and has never let him down. I had the more potent 325 WSM but my days of pursuing big nasties are history. I'd say get the 300 WSM and don't look back.

The WSM's aren't going anywhere. I love the 300WSM. A 7-300WSM might be in my near future too.

The only downside - and maybe this is better now - is that Winchester has been the only source for brass. Brass seems to last well though, a couple hundred pieces of brass will last a HUNTER a couple lifetimes.

So your saying it would last you or me what, a couple weeks? :D

If you reload ..............fine, use anything you have brass for & a gun to shoot it out of !

What is it that a .270 Win or a 7MM RM can't do ??
