what i think is interesting, is that alot of guys here complain about blowing big holes in fur, but yet want a super fast 22 caliber, the two are not mutually exclusive but close.
i can speak from experience, i had a 223 wssm. i bought it partly because it was fast, but mostly because i needed a light weight rifle for high country coyotes in the summer.
when i bought mine, an ultimate shadow winchester 70, i bought dies and 100 new brass. the dies were hornady, the bullets i was using were mostly v-max 55gr. while some of the issues i had were things that i probably could have gotten around, i got tired of trying to "fix" issues.
i was NEVER able to get anywhere near factory ballistics using imr 4350, i had flattened primers and heavy bolt lift with load no where near published maximum. i could probably have changed powders and gotten around that issue. seating the bullets required quite a bit of force, enough to deform the noses of v-max bullets, hornady sent me a new seat stem, but it was the same. i solve that issue by using a winchester bullet with heavier nose construction. again not a big deal, but something that had to be dealt with. the first 100 NEW brass started to crack shoulders and necks on the second or third loading. yes SHOULDER cracks. i tried annealing, to soften the necks and shoulders, i may have gotten a little better life after that but not much. i bought another 160 brass from someone on gunbroker, it was once fired winchester from test loads. i would start with 100 brass, next loading i had 65 or so left, then next loading maybe 30 left.
last i looked 223 wssm brass was about 60 cents a piece, if they last 4 times, then each shot cost me 15 cents just in brass! performance was only marginally better than a 22-250, but with brass that costs far more. i find enough 22-250 brass at the public range to last me a lifetime, i spent more on 223 wssm brass in 2 years than in 12 years with a 22-250 that i shoot way more.
if you want a 223 wssm, then get one. but i would take ANY other 22 centerfire before another 223 wssm. 22-250 is hard to beat for a varmint rifle or predator rifle.
