340 I was fortunate. Mine were very easy to get shooting accurately, in fact all my Weatherbys have been sub moa shooters. My "go to" rifle's always been my stock 300 Weatherby MKV Deluxe and with it I've taken over fifteen head of African game and over here I've used it on Black Bear, hogs, etc. I think where the Accumarks shine are on open terrain like the Karoo,out west in the plains or from fixed hunting stands and ranges are long. Were I hunting in the mountains and I wanted to use a Weatherby, I'd use one of their lightweight offerings.
