"The cold bore shot is pretty much on target then as it heats up they move right as much as 6 in when it got real hot"
Getting any barrel "real hot" can change things, sometimes drastically. Is the barrel free-floated? It may be when cold, yet it may not be when hot. Magnum calibers will heat a barrel fairly quickly, so it's important to time your shots to avoid over-heating the barrel.
It's tough for me to use patience at the range myself, because I want to "burn some powder". What I try to do now is bring another rifle to shoot while I let the other one rest. I'm learning that getting a barrel real hot is the worst thing for it. It causes accelerated throat erosion- destroying it's accuracy.
