hi all.this is my first post. I have been lurking on here since a fellow shooter turned me on this extremely helpfull site this spring. I have a rem sendero that I had trued and rebarreled with a pac nor tube that I got back a few weeks ago in 300 win mag. I replaced the bolt with a Ptg bolt and had the barrel set up with their pac nut which is basicly the same as a savage setup so I could change cartriges. I was thinking of getting a .358 wsm wildcat made to deer hunt here in indiana because next year the law will probably change to allow 1.8 in case lenth in rifles. Can I open up the old bolt face from.532 to the .535 dia.and still b safe? Will the extractor still work and/ or fit?
