[QUOTE="backcountryguide, post: 824909, member: 38531"] Guys I finally got some good conditions and went to the range to true up the drop chart. I am using shooter on my iphone and a Kestral to input my data. The chrono gives me 2975fps from 43.5gr of H4350 and a 140VLD. I input my station pressure at 23.4 with a temp in the low 80's. I dial in .2 mills for spin drift and .2 more for the wind. First round at 1009 yards is about 3/4 mill high but dead center for wind. I dial down and plant the second one dead ceater on the plate. Four more and we head up to check the group. A very nice 5in group with almost no vertical. I input into shooter what I dialed to get the group and it spits out my velocity is 3070fps. I say out loud that that cant be. We then hang steel at 500, 700, 900, and repaint the 1230 yard target. I start shooting using the new data and it is spot on all the way out with a 8in group on the 1230 target. Our range sits at 6500ft but I only input station pressure into shooter since the kestrel gives me the true pressure. The rifle has a 28in Bartlein on it but this seems to fast to me.
