True Grit, Having a gun range on the ranch is handy, but it's 6 miles from my house I do everything everyone else does when going to the range, I just don't drive as far as some.
Did you ever think of putting up a target just for your cold bore shot, in addition to you other targets?
Once I have a hunting rifle shooting groups where I want it to, I start trying to get my cold bore shot located where I know it will go 99% of the time.
here's an example of what i'm talking about 10 shots at 1000 yards 8 hits 2 misses.
Cold Bore at 1000 yards
Cold bore again 1000 yards
I'm not a big fan of follow up shots at any distance I want to know where my first shot is going at any distance. Rio7
