Well my plan A, B, C and the rest of the alaphabet has gone down the tube. I was hoping to build a LH Model 70 Featherweight in .243. Since all LH model 70's only come in WSSM and WSM calibers and the bolt face can't be changed it looks as though I'm going to have to settle for a LH Model 70 FW in 243 WSSM. Does anyone know what the ballistic differences are between these two calibers? I'm planning on reloading all my ammo and like my sons 243's I want to stay with the 95 gr bullet for deer and hogs. Will the WSSM buy me that much more velocity over the standard .243? As always, thanks for your input.
