Thanks again to all for the info provided.

I bought a used 1954 No 4 Mk 2 "Irish Contract" Enfield a few weeks ago. Had no luck finding brass for it and the only bullets I could find were 150s but I found five boxes of older Hansen 174 FMJ ammo mfg. in what used to be Yugoslavia so it's got to be at least 30 years old. I read somewhere Hansen was the import name for PPU, which IME has always been decent ammo. I shot 40 rounds of it yesterday and had no problems with it. Went bang every time and 100 yard accuracy with the 300 yard flip up battle sight was well centered, 6" high and averaged around 2& 1/2" for 5 shots so can't complain. The brass looks good so I'll see how it does neck sized with a light load of 40 gr of 4064 and the 150s which are also PPU.
