View Full Version : Winchester Wssm

February 2, 2006, 04:45 PM
There are some 243WSSM and 223WSSM rifles at a good price and I was thinking of picking one up. will the barrels be prone to burn out at a short time ? the ballistics look pretty good. I also wonder how long ammo will be avaliable? anyone know anything about these ?

I don't, but I'm interested in the 25 WSSM... So consider this a bump in the interest of getting someone to answer yer related questions! :D

In an AR15, the .25 wssm is quite interesting to me. Almost .25-06 ballistics in a semi-auto, accurate platform? Hmmmm. Yeah, barrel burnout is gonna be too much on the .223 or .243 wssm.

The WSSMs, generally, are maybe 10% less velocity than a lot of the magnums, but 20% less powder. This is said to be due to better efficiency that comes from the cartridge case dimensions. I'd guess that barrel life would be better than the magnums, but maybe not as good as the standard-velocity stuff.

I don't see where they'll perform a whole bunch better than a lot of existing cartridges. But: If I didn't have a .308 or .30-'06, I can sure see where a handloader could do well. You can load down for plinking; medium for the typical whitetail hunting, or full power if you go into elk country.

Same sort of deal for the smaller-diameter cartridges.

The pitch on Winchester's site shows a favorable comparison of a [I]chrome[I] WSSM barrel to a carbon steel 22-250(apples to oranges??). Looks to me like the 223 has a fair barrel life, and I would expect the 243 and 25 WSSMs to last a little longer.
