Take for instance the steyr 1894 receiver I'm currently doing. Lotta small pitting on the receiver ring, pitting at the woodline on both sides of the receiver. I'm trying to cleanupthe receiver ring with out messing up the oweg
steyr
1894
Problem now is instead of having only a few large pit I now have a bunch of little ones on the receiver ring. Right rear receiver had a bunch of bad pitting, managed to reduce this down to one small pit. Left receiver wall had a lot of fine pitting. All gone except from where the gew88 is stamped. I am of the opinion that these actions were case hardened. Its definitely not soft metal by any means. In some cases where there large pitting I have now got little pitting. I took the time and checked the FN action getting worked over. I did not use a stone that large. I used a 3/8 triangle stone with some silicon carbide paper wrapped around it. The stone basically acts like a support surface for the silicon carbide paper. There is some fine pitting around one of the bolt stops two holes. Wish I could send pics but am technically challenged. That about it so far.
Thanks all for your suggestions and help. Frank
