Home Forums Hunting & Shooting Long Range Hunting 7mm WSM with heavy bullets?

And all I want is some reliable data on 180s in my 7x300 wtby.... using 7stw to start... but Eric at Berger says go with 300 wtby data for 180s.... wth... its only 10 grains of powder difference between the two.... makes one wonder. And then... use a chrono.. but what is max anyway...

I run 168 berger at 2980 from a 1:9, 24" Broughton tube.
65.5 grains of I7828ssc over a 215M is my accuracy load.
I have run it faster, near 3100, but accuracy was not .5" or better...which is my personal goal for accuracy.
Max load of 7828 is @ 67 grains in my set up.

I loaded for a 7mm WSM over the summer.
Not mine.
Dober dude.
You need one of these things.
I ran 162g A-maxs over H4831sc with russian primers out of a old 722 action and a Douglas barrel.
Little, and I do mean little groups at 300 yards.
The I guy I loaded it for is usuing it right now for deer.
Im waiting for a hunt report.
