.223 WSSM or WSSM IMPROVED

[tbrown9124]

I was just wondering if or how many out there have experience with this cartridge or wildcatting it, it just seems to be the best of the wssm's in terms of potential. just fishing for thoughts on this round good and bad

Seems like everyone else says it the worst one.

I'm no expert here but this is what it looks like to me.
It looks like Winchester just took the same case as the WSM
line, cut the front off and necked it down to form the WSSM
line. But this leaves you with a very thick neck on these cases.
All other 224 cartridges have an outside diameter on the neck
less than 0.260. The 223 WSSM is 0.272. The really accurate
rounds like 22 PPC and 22 BR have outside necks at 0.246.
That's a huge difference. Very thick brass in the neck area.

I don't hear anything good about these rounds. If I wanted
a really hot 224, I'd look elsewhere.

I have never shot it or loaded for it, but I am balistically familiar with it. The 223 WsSM has minimum body tapor and (I was going to say 35 degree shoulder, but it its actually 28 degree). It is at the upper limits of practical case capacity for the 22 IMHO, so I wouldn't improve it unless ya just want to say you have one. There are hotrod 22 out there, but when you push so much powder down the tube, you are going to see some very limited barel life. I don't claim to be an expert, but that is my opinion - maybe ya weren't looking for that .... oh well

Well i lovee hotrod 22's and as for potential i mean in terms of eavy 22cal bullets 70gr and over, barrela life and wear are the dues we all pay for all out performance one of my fave rifles is a 243catbird it eats a barrel at about 900rds fired so every year and a half or so it gets a new tube. I was just looking at the round as a 22 that i didnt have and may want to get it certainly seems to have the steam behind it. I think i read somewhere on here that Kirby allen played with it when trying to make a 224 allen mag. I have seen the 223 wssm in an ar platform and the gun shot very good at longers distance i was just thinking good barrel and builder and heavy bullets it could have some real long range potential that cartridges like the 223dont have and could be better than some of the other hot 22's like a weatherby rocket ,swift or 225 winchester or the necked down 284. just food for thought

I am in the process of biulding a 223 WSSM and have done quite a bit
of research and will post the results as soon as I get finished .

This cartrige is so overbored that I was not interested in wildcating it.

After deciding what bullet I wanted to use and the expected velocity
I talked to several barrel makers and decided on a Lilja 3 groove with
a 1 in 15 twist.

I posted a thread on 3 groove barrels and got a lot of response (Good and
Bad) .

Barrel life is an issue but not a tie breaker.

I also receved some good advice from kirby about what bullet to use.

Hear is what I am going to use in it = A 40gr nos balistic tip @ 4400+ ft/sec

I am currently using a 220 Swift with this same barrel and bullet @ 4200 ft/sec
and I am very impressed, accuracy is less than .100'' and the barrel cleans up
with just a few patches (3 or 4 and the copper is gone).

So now I'm stepping it up and I hope the results will as good or better.

We dont have the P dogs and muskrats in south texas but we do have Bob cats
and coyotes so barrel life is not an issue.

If you finish yours befor I do please post the results.
