I need some help. I am trying to find some 162 grain (hornady bthp) for my 7mm Rem. Mag. I have a rifle that has a Redfield scope and range dots put on by Premier Reticle. The "problem" is that it was loaded at the time with the old hornady bthp match bullets. I cant fined them anywhere. I did find some 162 Amax but I believe that they have a different BC. Any help would be appreciated.
