Previously, I discussed an extraction problem I was having with my Safety Harbor Firearms UltraMag 50. One week ago, I finally made it to the range to test the theory out (that I had cleaned out the carbon and all was well).
I want to report that I had no problems with extraction with the 5 or 6 rounds of 50 BMG AP I was able to shoot before the neighbor cut us off. Close inspection when I got home revealed the chamber is now lightly coated in soot; before shooting, it was a light gray color. This leads me to think that David's theory of an incomplete neck seal combined with my poor cleaning habits lead to the situation I was in. The KNS anti-rotation pins, of course, had no problems holding the hammer pin in place. The SHF hammer doesn't have a spring and pin in it to hold a standard AR hammer pin in, thus the issues I had with the hammer pin walking out. In short: all's well; I now know religious carbon scrubbing is a part of the routine I need to stick to. |
