[QUOTE="Guest, post: 36779"] By "338-358 STA" I mean the 358 STA necked down. To make the STA Simpson decided to improve the taper on the 8mm Rem case a bit. By necking down the STA you're doing the same thing as a 338-8mm Rem Imp. As far as pressures go, that's all up to you (assuming you roll your own.) The 340 will be cheaper in some ways, and you'll have load data. Though any of the wildcats on the 8mm Rem case will be close enough that you could use the same starting data (or maybe back off another 2%, but the difference in 340 pressures might be the difference in STA capacity, if you know what I mean.)
