I also had the stock trigger worked on and pillar bedded the stock myself.
I don't know about anyone else, but I wouldn't push a 180 out of any 300 win over 3000-3150 fps. I'm at max. pressure with a lot slower powders with 180's at at least 100 fps down from the 3240 fps quoted. I'm not saying you aren't getting it, but you've got to be rather warm as far as pressure.
Perhaps someone could quickload a 180 with the about charge of 4350 out of a 300win; extra velocity isn't free pressure wise.
