Has anyone opened up the .222 sized bolt face on the older 46/461 Sakos to accept a PPC case? I know the later A1 rifles came in PPC calibers but I think the extractor is different/shorter on those. There appears to be room on the bolt face, but I don't think the standard extractor would work correctly.

Good question, and I don't know the answer. I would also wonder whether the feed rails are different for the fatter case.
I have two A1s in 22PPC, not for sale, but if I cam give you and info off of them, let me know.

Thanks for the offer, I may get back to you. Feeding from the mag box would be a nice enhancement for one of the two rounds I have in mind which is a 30 cal Improved Grendel. The other would be a 22 or 6PPC and single shot is OK.
Could you post or email me a closeup of the bolt face and extractor on your A1?

Still like to hear if anyone has done this on an older Sako.

I once had a 30-06 Sako Bolt opened up to magnum caliber, before I was doing my own work. A simple matter to put a drop of weld on the underside to allow it to slide over the bigger case. Might be something to try. Opening up the bolt face should be no big deal
