I have a new 7wsm and I am trying to decide if I should use H4831 or H1000. The rifle has a 28 inch barrel and I am tending towards the H1000 to take advantage of the barrel length. I will probably use 162 A-max for most shooting, and something with a better jacket if I use it to hunt. I have reloaded for over 40 years but never to the exactness I will need to do to have this shooting like I hope it will.
