I know who you are!!!! Thanks for the flatery and I give you a hard time because I can, if you are nice, I will let you shoot my double now that it is finished next time you are up.
Now for the P-14 and P-17, these actions are mostly over looked, probably because of the machine work needed to turn this ugly duckling into a swan. All this work can be done by hand but a milling machine and such speed up the tasks. The big Enfield action will easly handle the bigger cartridges such as the .416 Rigby and some have even gone as far as the .505 Gibbs though this is pushing things a bit but the action will take it. The best part of all this is that these actions are cheep and readly availably in their butchered form.
I would not recomend the Enfields for the short cartridges such as the .308 or even for the standard length rounds like the .30-06. You will end up with a heavy rifle or one where you have a very long bolt travel or both. The Enfield comes into it's own with the magnums and the big stuff. I do not like counter bores so I fit a P-14 bolt to the P-17 action or just work with the P-14. For a standard magnum you will not need a counter bore or extractor cut if you do this and in most cases will not even have to open up the bolt face.
Many people feel that the bolt handle on this rifle is rather ugly and want to get rid of it's "dgo leg" look. I have found that the best way to do this and also get rid of the unsightly hole in the bottom of the handle is as follows. First straighten out the handle, you will need a oxi torch for this. Then cut it to length as it will end up way too long. Thread the cut off bolt knob and the bolt shank and screw the thing togther then weld all the way around. Next cut off the remains of the stub from the knob and clean up every thing on the bench grinder and with files. This is what I did on my .366 DGW and then I did a five panel checkering job on the bolt knob for grip. If this picture comes out you will be able to see what I am talking about.
