Browning and Winchester recently released the test results on the Super Shorts and Petersons Hunting did an article on it in this months "Hunting".
It seems that all the naysayers were wrong again... just like they were with the Short mags.
None of the test barrels showed any signs of excessive throat errosion or barrel wear after thousands of rounds fired.
In fact they found that with standard, non-chromed barrels the wear performance of the WSSM's is equal to the .22-250. In Chrome-Lined barrels the wear resistance and accuracy longevity is DOUBLED!
It should be noted that Winchester/Browning has never sold a .223WSSM or a .243WSSM under their brand name without a chrome lined barrel!
Regarding the 25WSSM none of these issues are a factor as the velocities are virtually identical as the 25-06 and thus presents the same wear profiles as the old cartridge.
How bout them apples
