Can someone help me with why sierra publishes 175's to be fired from a, no less than, an 8.5 twist barrel? From the data I've found, and from loading the 7mm win and 7mm stw, a 175 smk should stabalize, at distance, out of a 9.5 twist barrel, if its loaded up to around 3100-3200. Please correct me if I'm wrong. Thanks.
