[QUOTE="elkaholic, post: 1324627, member: 13833"] Here is a comparison pic of the SS vs the SST. Left is the SST with a 140 Berger Hybrid and the SS is loaded with a 143 ELDX. The shoulder/neck junction is .003" forward of the SS on the SST so a person could shoot SST ammo in the SS chamber with proper head space. Body taper is the same and of course the SST has the 30 degree shoulder vs the 40 on the SS. Case length is identical and the SST has a shorter throat. Early results indicate that the velocity difference will likely be around 50-75 feet with equal barrel length and pressure. The SST can be cut to trim length BEFORE fire forming as it only shrinks about .002". Head spacing is precise when the shoulder is pushed back correctly as it remains at 30 degrees ...........Rich [ATTACH]77186.vB[/ATTACH] [/QUOTE]
