Swiss K31

 Took the Swiss K31 with the Hi-Lux LER scout scope to the range. I loaded 3 bullet weights as a first determination as to what weight I should do additional testing. I have 150, 165 and 180 grain bullets, I arbitrarily picked IMR 4350 for the 180, and 4064 for the other two. Three shot groups at 100 yards with the 150 and 180 grainers were about 1-1/2 inches. That was about as I expected. for an old military bolt action. The 165 grainers were quite a pleasant surprise, with a group of about 5/8 inch and 2 in the same hole.

I will repeat the test, but I expect similar results. If that happens it'll be the easiest and quickest load determination I have ever experienced.
