  Can't remember the exact year we stopped loading corrosive -06, but I believe it was prior to 1955. Not sure about other countries.
  Yours is 1959 or 1960 vintage.
  Corrosive refers to the priming compound used, and the residue is easily nutralized with water soaked patches ahead of (before) the standard solvent clean and oil process.

  Re headstamp, believe your ammo was loaded in Taiwanese ( Nationalist Chinese ) military arsenal. Whether they were still using corrosive primers as late as 1959, is a question I can't answer?

  US started non-corrosive in '43, but there is no way to be certain about other mfg. Since the Taiwan armory was set up by Winchester, one would think that it is non-corrosive. It is fairly easy to test. Get a piece of unplated carbon steel to use as a target. Pull the bullet and powder from a cartridge and fire it, point blank at the steel target. Remember, the only corrosive component is is the primer and you will have spread its by-products on the steel plate. Now, just check for rust in 24 hrs.
  Good luck!

  I thought it was at the end of the war about 1953-54 that we stopped the crrosive USA ammo?

  CANADIAN production .30 carbine ammo often shows up in GI bandoliers, and stripper clips. sometimes it is packed or repacked in GI cans. it is corrosive!!! it looks just like GI US production ammo, and the headstamps can be easily mistaken for US arsenal manufacture (the used the same headstamp pattern, ie. arsenal over date code stampings). this stuff was produced ito the mid 50`s. just a word of caution to carbine shooters. best regards, mike.

  I cannot tell you whether it is corrosive or not, but I can say definitively that no one above gave you a precise identification of the ammunition. This ammo *was* produced in Taiwan, at the Kao Hsiung factory (code 60A); Japanese military .30-06 uses letter codes in English and Western dates. It was *not* produced in 1959, but in 1971 - the headstamp reflects the *Chinese* year, not the Western calendar. The "30" is the caliber - you will see this used on British military .30-06 of the 1950s and several other nations' production, also.

  Soapy warm water and don't forget the whole gas system and the face of the bolt......I would treat all foreign ammo as corrosive...........BEST OF LUCK........john.........
