Use for RRB case deflector
Jim:
There is one opportunity to use your thinned down mainspring. If you attach a case deflector to the hammer spur, cut your load a bit & place your ammo in a loading block, you're all set for the Semi-Self Loading RRB match. Perhaps we can get the CMP to add this as a specialty match at CAmp Perry!:)

This started out as a 43 cal Spanish rifle from Hunters Lodge in the late 50's. I squared-up the receiver, made a new trigger and sear to get a nice pull and still keep the mainspring. Also bent the tang and had a blank of Calif walnut which I used to stock the rifle. Also made the scope blocks.
I converted the breech to 22rf but could convert it back to center fire by changing the bushing. I bought a 3/4 in 22 rf blank and cut the original barrel to ten inches then bored it out to half inch. I then turned down the last ten inches of the 22rf blank to fit the old barrel.
I sent the action to Cody WY for a case color that cost $65 (ten years ago)
