I have a 300 wby accumark. It is an accurate rifle. Recently I was talking to a guy in the weatherby custom shop and he pointed out that on the synthetic and stainless synthetic, you get a plastic stock. He made it sound like this reduces accuracy. I am not so sure how much. I was asking about a 257 wby and asked which he prefered whether it be custom of not and he mentioned the accumark, lightweight or super big game master. Handloading, you can produce some very accurate rounds.
