Nice rifle but I would like it more if it had a wood stock but I am a traditonalist so what can I say, I guess I am a stick in the mud but that is just the way I am. However this proves my point about the Enfield being a great action for the big stuff.
Now if you look at the picture of my action you will see how to get rid of the "dogs leg" bolt handle. First you fordge it straight then cut it off to the length you want, save the knob! Thread the shank and take the knob, thread the hole in it, crank it on then cut off the excess and weld all around the threads. Next, reshape the knob and in this case I did a five pannel checkering job on it.
The action can be cut back quite far nearly all the way to the ejector. On the left side of the action more metal can be removed eliminating the button for the bolt release however do not cut forward enough to remove the camming serface for primary extraction!!!! No metal should be removed from the feed ramp, or lower recoil lug or not more then what is the thickness of the top lug. This will weaken the action and is why it is not recomended by many gunsmiths to open this action up for such cartridges as the Gibbs. The 505 is fine in this action as it is a rather low pressure cartridge but let some hand loader who has dreams of 585 Nyata performance load for it and you could have problems.
