I measured my bolt and it actually had a slight taper, .693" in the rear and .695 in the front. The PTG Bolt measured .700" exactly. He was gracious enough to let me stick the new bolt in my 721 and give it a few vicious dry cycles. TADA! It ran slicker than a honeymoon erection! I hope this helps anyone that ever runs into this problem.
With the bolt being tapered no wonder it was binding.
When/if you buy a bolt from them tell them what size you want and they will grind it to that dimension.
Be sure and check your head space with the new bolt. You can buy a head space Gage from them
at the same time. You can use the GO Gage and place shims between the bolt and head space Gage
until it won,t close and then measure the thickness of the shims for the head space. Note; do not force the bolt closed just normal pressure on the bolt handle.
Also you need to remove the ejector to get a good reading. Leave the extractor to extract the Gage.
