Had a interesting thing happen yesterday at Connaught was shooting at 1000y F class shooting a factory .223 75gr bullets had shot in morning at 500,600 and 800y witha load with 25.3 gr of powder. Took a break for lunch and shot a ten and 15 shot rounds at 1000y
Ran out of ammo with 25.3 gr and had to use some I had loaded with 25.5gr
but felt they where a little warm. I had been shooting well for me shot a 47 with 3V bulls at 800 y conditions where quite good about 2.5 min for wind and mostly constant the odd little wind switch.
When I shot the 25.5 load at 1000 I almost shot over the target at 12 oclock, my partner said what happened there I told him about changeing load he could hardly believe that 2/10gr would do that much change, as my verticale was very good all day. I came down 2 minutes and was still high had to come down another 3/4 min too get back in to bull, that well over 20"
I use a electronic scale and it weighs within .01gr, guess a fellow shooting a 223 loading with beam scale would have quite a bit of verticale.
