I posted on this some time ago but didnt get to much input so I'll try again. The barrel on my win mod 70, 300 wm is toast so Im looking at going with a Kreiger ss and chambering in 300wsm. Now Ive read that this caliber doesnt do well with the heavier bullets. I prefer the 200gr.spbt and want to try Berger 210's. Is the reason this cal. doesnt like the heavier bullets because of the short action so reduced powder capacity with longer bullets? If so a med. action shouldnt be a concern with this I would think. Should a person go with the 1-11 twist that Berger suggests and hope it does well with the Sierra's or go with standard 1-10 and hope it does well with the Berger's?
