I went to shoot my brand new 10fcp-hs today. Last night I made-up some loads for it. 5 of each load: 42.5, 43, 43.5, 44, 44.5. I needed to zero the scope so I made 10 extra 43.5 (middle of the road). I wet patched then dry patched between every 2 rounds and was not in a rush (it took me 2 hours to fire 35 rounds). I zeroed the scope @ 100 yds (just 1/2" high and right). I then proceeded to check these loads.

6-1/2" down and 2" right (best group @ 3/4")

why would the rounds switch from zero to 5" right, then go crazy w/ the zeroed load, then drop 6" and come back left 3"??????

It was gusting wind but, like I said, I was not in a rush. I waited for dead calm to fire.

I am going back out saturday w/ more 44.5 and some 45 and 45.5. Then I'll mess w/ the inbetweens and length.

Oh, I worked-up some subsonics using 220 SP's, 9.3 Titegroup, flashhole @ 9/64". 990 fps average 50 degrees, 65% humid and 396ft above sea level. I believe barometer was about 30.2 ish.
