What is best ammo for 300 win mag?
To get the best acurecy out of a 300 win mag would be to start
reloading;moly coated 175 grain sieara matchking, N560 vita vuri
powder and winchester brass. Expierment with with diferent charges
I had the best luck with 75gn. BUT! the older models can not take
that hi of charge. Seat the bullet out to about five thou. behind
the rifling. but if you dont want to reload then the best ammo
would be
BLACK HILLS ammo with 175gn matchking molly
note
the matchking does work great for hunting "great expantion"
