Well, this time I think I can probably risk using Gary's broached blank rather than starting with a bar stock...
So I got a long action, magnum bolt, Gary's blank, and a 300 win mag barrel. Blank is already broached so the bolt fits nicely. All that is needed is ream and thread the front, machine the back, the magazine well, the ejection port, cams, etc. and it should be shootable.
The only problem is, as of late I had very little free time. Calculus is kicking my butt and so is physics. I'm also doing research on the side so I haven't gotten a lot of time actually operating the machines. The only thing really giving me pause is trying to find the right orientation (making sure the raceway is exactly parallel with the machine table) so I can machine a flat onto the blank. However there really isn't a lot of material for me to do that. Not to mention I really don't want to make a mistake on a 250 dollar blank... those 4140 bars cost 12 dollars each so if I mess up all I lost is the time.
