How to adjust a BOSS on a Browning? And 300 Win mag loads?
I have made a few posts about my .338 Lapua in the past.
Now I want to tune in my wife's 300 win mag for long range use. It is a stainless A bolt stalker with Boss, and a 4X 14? Varix X III leupold, with a stoney point target turret for elevation adjustments.
My quandry is that it has a BOSS. That seems to add yet another variable to deal with in the reloading.
Any suggestions on fine tuning the BOSS without expending 1000 rounds? And for that matter, any suggested loads for long range 300 win mag?
And what ranges are you making hunting shots with your .300? I would be happy if we can dial it to 600 yards...
