tinkerfive Posted February 28, 2010 Report Share Posted February 28, 2010 OK, this is a point of curiosity. I'm certainly not familiar with every bolt action out there but how many have 2 torque shoulders in stead of one? I know that he P14/P17 Enfield didn't and they are very desirable for magnum actions. I was wondering when Remington started making the 798 if they might thread them at 16 tpi and eliminate the C/H ring to use the same barrels as the 700. All they would have to do is adjust the shank length, eliminate the 'tits' on the bolt like a Yugo and make an extractor cut. Could the barrel shank be lengthened and the C/H ring eliminated or, does it really serve a vital purpose? Now I know from pulling plenty of military barrels that the shank was only 1.1 and left nothing to torque up to the "secondary" shoulder. I'm asking in regard to if you had a barrel shank configured like a Remington or the P14/P17 Enfield. Tinker Quote Link to comment Share on other sites More sharing options...
724wd Posted February 28, 2010 Report Share Posted February 28, 2010 rem would never change the barrel since they didn't make the 798's. all they did was import them as zastava made them. the C/H ring adds another layer of safety that is beneficial to action strength. without it, you'd have the pre-98's. the p-14's and 1917's make good big calibers because the physical size of the action doesnt require the work like a standard 98. i'm sure if given a choice, most builders would choose a magnum mauser action over a 14/17.

ken98k Posted February 28, 2010 Report Share Posted February 28, 2010 The c-ring adds strength to the Mauser 98. Most manufactures, including Winchester and Remington opted to skip this feature. Most likely to save money during manufacturing. I don't know about Savage as I don't own one. I just bought a couple Parker Hale receiver castings; one is an m98 copy and the other is a Midland (hybrid Mauser 98 that uses a Springfield bolt) and neither employs a c or h ring.

Rojelio Posted February 28, 2010 Report Share Posted February 28, 2010 Ken, do those receivers still have to be heat treated? Quote Link to comment Share on other sites More sharing options...
gun nutty Posted February 28, 2010 Report Share Posted February 28, 2010 Those PH receivers need to be threaded, then heat treated! Or is the pic not showing the receiver threads? Quote Link to comment Share on other sites More sharing options...
machinist1 Posted February 28, 2010 Report Share Posted February 28, 2010 Gents, The purpose of the notches in the internal ring is for machining. The rail ways are broached in the action. Origionaly there was only one notch ( c-ring). The scecond notch was added as a way to cut costs of machining ( h-ring). Bob Quote Link to comment Share on other sites More sharing options...

ken98k Posted February 28, 2010 Report Share Posted February 28, 2010 Ken, do those receivers still have to be heat treated? Yes. They need everything. They are just raw castings, don't even have serial numbers. Quote Link to comment Share on other sites More sharing options...
brokengun Posted February 28, 2010 Report Share Posted February 28, 2010 Ken do you know if they have anymore of those castings? Ken I don’t know if you’ve seen this free book or Not but this might help you “A guide to the drilling reaming and broaching a bolt action receiver at home” by Raymond Benwood Don’t be afraid to share this book with others. The author on the 1st page in his book asks that his book be shared with others freely. In fact he says that it is his personal desire that his book be stored copied and shared with others for the purpose of promoting a 2nd amendment culture. These links were active the last time I checked. The JPFO link is No longer available on their page but is still active. The scribd links seem to be the best. I suggest everyone makes copies and share with friends while this type of info is still available. I printed out a copy so I could see/have the template’s that are used to cut/mill the magazine feed lips and ramp area http://www.scribd.com/doc/3615602/BA http://www.jpfo.org/filegen-a-m/boltaction.htm http://www.scribd.com/doc/14066913/Selfmade-Mauser-bolt-action-receiver Quote Link to comment Share on other sites More sharing options...
