Got around to shooting at 500 yds again

It was nice this morning, with very little wind so I went out to the 500 yard range to give my new load a try. Winchester brass, Winchester WLR primers, 35 grains of Varget and Hornady 162 grain A-MAX 7MM bullets. These bullets are for a 1-8 twist barrel but they seem to work in my 1-10 twist 7-08 well enough. Five shots from a rest on a table, the first was short by about a foot {my mistake in judging the 69.8 inch drop}
