According to everything I have read in every book I have...they never made the left-handed BDL in anything but those 4 calibers I posted. That being said I have seen a couple 308's previously on Gunbroker (none lately) and I have also seen a 22-250 for sale before on Gunbroker...but it was built on a former 270 action. I have a 270, but it shoots so well I refuse to use it for my donor gun...I also have a 7mm Mag, but it has been to the Remington Factor Custom shop for work and again...it shoots so well (and has a few $$ in to it) I don't wanna tear it up either...haha. So, ya got one laying around RR?
