[QUOTE=mapper;174344]So how far down the rabbit hole do you go, all the way to the David Tubb suite?
I got pretty deep . I have good equipment and in my opinion some first rate rifles. That's what let's me know I'm a minute of angle shooter.I have a friend that's capable of shooting 3/8 inch groups with the same rifle and ammo. One thing that I do is mark any case that is a flyer then when I load it again I'm extra careful with it . If it's out of the group on the next firing I throw it away. I don't waste any time trying to figure out what's wrong with it. That step along will tighten up your groups measurable .

I have often wondered what diffrences it would make, but haven't bought guages to be able to tell me any errors, or changes in procedures or equipment to reduce them. So I park in the gravel lot and make ammo as consistient as I can. That's pretty much the way I started and no better than I can shoot it would have been all I ever needed.
