I have read a lot of great info on here regarding 300 win vs 300wby. If a person hand loads, what are the actual real world speed differences between the two? Also, I see a lot on the web about potential accuracy issues with the wby, is that a concern? I have several 300 weatherbys( all factory Rem or Wby rifles) and have not experienced poor accuracy personally, but I'm a novice. Thanks in advance!
