Just got a 300 win mag R1 and was wondering how everyone is doing on long range shots with factory barrel? I was trying to get good groups at 300 yards and was having some difficulty... I had 10 or so shots down range so my barrel was hot and I had a slight cross wind with 150 grain bullets
How much accuracy loss do you see with a hot barrel?
What rounds does your gun like?
Did you adjust factory 8 lb trigger?
