Great action and very under rated. I have bolts for both P-14 and P-17 actions in my shop give me a call 207-938-3595. If this is a project gun let me know as I have a bolt that has already been re worked. If you are doing a magnum the hot trick is to fit it with a P-14 bolt then you do not need the counter bore or extractor cut on the barrel. Like I said, these are great actions and will swallow up cartridges .416 Rigby size and larger. P-14, 17s are one of my favorite actions to work with when a customer wants a "big" rifle, they also make a great 45-70.
