Many here try to apply benchrest loading techniques to a hunting rifle, they're not built to the specs of a benchrest rifle and won't respond to worrying over minutae. Keep it simple, most loading manuals list a most accurate load, my preference is the late Ken Waters Pet Loads, using these loads a lot of the leg work has already been done.
It's gotta be said.....
I would tend to think that in many cases it's just a hunting rifle, because in many cases people can't shoot worth a fu ck, because in many cases people buy a cheap dog shi t rifle and it won't shoot worth a fu ck no matter what, because in many cases people are just too damn lazy to understand the basic science of making a rifle shoot worth a fu ck.
Etc.....
It's just a hunting rifle saves a lot of faces in an alpha dog internet world.
