Hi guys, I've tried a couple of barrels swaps, but not one that required a different bolt head before now. I am trying to convert one fo my .270's to a 300 win mag, but when I got the slotted screw bolt apart, I found that it had the large firing pin diameter, then I took the hex head bolt apart and it also had the large firing pin diameter.

I had ordered a new magnum bolt head from midway, and needless to say, it wouldnt work with either of the bolts that I have.

Can i still find left handed magnum bolt heads that will work with the old style firing pin assembly? If so where do I find them?

If that isnt an option, can I swap out firing pin/striker assembly to the newer diameter? Would that be an easy swap or will I have to change/ modify the bolt body?

Where do I go from here?

thanks in advance,
