What a science it is how some rifles prefer certain weights bullets as much as they prefer certain charge-weights and seating depths.
My elk rifle, an old safe-queen Savage 7RM I traded a horseshoeing and a mule trimming for. Shot all over the place with anything you tried. So I made a couple piller-blocks and glassed-in the action. Serious Improvements!
But a work in progress, it's real finicky.
The only thing that seems to work real well is 140s . And they only like the very upper spectrum velocities, that is fine with me!
I did luck out.
Before I glassed in the action, I did scrunch the magazine in a vice a little to make it a little longer. Turned out to be a good thing.
The OAL that shoots the tightist , just barely clears the box.
Two years and two elk with this one.
I did add a little more glass about 3" into the barrel, in hope that it would be less finicky. But have not loaded any changes yet, not sure I need to?
It is doing it's best with about as hot as you can go!
