I'm in the market for a custom rifle (Rbros, gunwerks, and such) in 7mm or 300WM but I have no experience reloading nor do I really have the time or desire to do so. I'm a novice to this long range hunting and this seems to me to be a VERY critical component to shoot and ethically hunt say out to 700yards. I see gunwerks offers custom loads specific to their guns. Are there others that offer this. I know most builders will send you the load info so I would not have to work that information up. Does anyone have a custom that shoots factory loads with the names above?
