in my (humble) opinion the smaller wssm's - 223 and 243 - are dead in the water. browning have just had a sale in australiawhere rifles in these calibres are down to half price, coz they can't shift them. do either of these rounds do anything that something else already can't? yes, they can burn barrels and throats quicker than the standard calibres! anything that dumps a large powder charge into a narrow bore has this problem. if the case is short and fat, the problem is made even worse.

the cases are hard to make feed cleanly, too.

and with the 223wssm in particular, it is still just a 22cal projectile, and therefore just avarmint cartridge, so you'd expect to fire a lot of rounds. i'd opt for the 22/250 or 220 swift, myself.

as for the larger wssm, that might be more practical, because you wouldn't be as likely to put hundreds of rounds through it. but i still think other, traditional rounds would be preferable.
