Six of one - half dozen of the other.If your a Remmy man you will choose the SAUM,if your a Browning/Ruger/Winchester man you' ll probably choose WSM, if you like Savage you can pick either

The two are for all intents and purposes about the mirror image of each other and for that reason one will probably fade out with time.Which that will be at this point is hard to say,the 300 and 270 calibers appear to be dominating the WSM line right now but there doesn' t appear to be a clear cut winner yet in the 7mm line.True there are a lot more makers chambering for the WSM line and that coupled with ammo availability seems to point to the WSM line staying in the lead for the time being.Haven' t seen rifles and ammo at Wal Mart yet for the Remmy but they always have the WSM offerings.If there is one caliber however that Remington stands a chance of winning in the short mag wars with winchester on, it would be the 7mm because of their long standing 7mm mag success.If they stay in the fray and don' t concede to winchesters constant new developments in the short mag arena I think the winner in the 7mm short mags still has yet to be decided.I do however think the 338WSM when released will be another winner for winchester.Tim,your velocity figures are wrong in the recoil charts you posted,look at the info above in Whelens post for correct numbers.Less recoil and slightly less velocity for the SAUM rounds compared to the WSM' s.
