Here's a target from a customer's 7WSM shooting a 175 Sierra shot at 300 yards that I did for a custom load work up. The rifle is a semi custom rifle with a high end scope. You can see Load B was the best shooting load. 4 shots in 1.105" at 300 yards (and I pulled 1 round slightly high). Not too bad!

Load B looks great. What is the load?

I don't have the data with me, but it was H1000 powder, Winchester brass, Sierra 175 Game King, Federal 215M primers. It's in a long action, and the bullet was seated out further than normal. Load B is slightly under max charge, and Load E was slightly over max, and Load F was over max charge and HOT with sticky bolt lift and shiny spots on the case head.

180 bergers and H4831SC does wonders in a 7wsm

That is a good combo!! Are you using a long action for the 180's?

good job

Short action, built by GAP.

That is some good work chad.
