The WSM is fatter than the 6.5mm Rem.Mag. the 6.5 rem mag is based on a shortened 375H&H and has a belt

the WSM is close to a shortened 404 jeffery, believe the RUM and SAUM are based on a 404 jeffery, so the WSM is close to that.

believe the 6.5 WSM is called the 6.5 Leopard

if I wanted a 6.5 I'd get a 6.5-284 Norma I think.

the 270 wsm is more popular than both the 6.5 RemMag or the 6.5-284 if you ask me, though the 6.5-284 will only continue to get more popular

Is your 270wsm by chance built on a long action? a 6.5 or 264 weatherby would be a helluva cartridge, weatherby should release one...

there's always the 264 win.mag.

the 6.5 rem.mag is skinnier than the WSM case though. not sure your bolt face or barrel will work.

btw what exactly is the problem with your 270wsm??

if you reload and want to move to a less popular round that still has velocity and BC's, checkout a 7mm SAUM, or 7mm WSM, just get a new barrel and you're set.

I think I'd keep the rifle in 270wsm how it is, and either keep it or sell it, and get a new rifle how you want...

remington came out with the model 673 a few years back in 6.5mm rem.mag. with a 22" barrel I believe, just buy one of those if you want a 6.5mm RM, or have ER Shaw build you one for $800 however you want it...
