[QUOTE="cowboyarcher, post: 837839, member: 14163"] Finally some velocity numbers for the 175's for you guys. By shooting at 300 and 400 yards and then working back I was able to calculate that the 175's over 58 gr of H1000 are leaving at about 2710 FPS, based on the average drop from 3 shot groups using a BC of .680. These maintained sub-MOA at 400 yards. I have not hit any pressure signs with these yet, so I may work them up more when I get another batch of bullets. The 165's jumped up to 2 MOA at 400 yards, so the average drop was not a very precise way to calculate speed in my opinion. I was disappointed in these, and am out of them, so I'll concentrate on the 175's for now. Here is the target: [IMG]https://lh6.googleusercontent.com/-hrDprsqRCjI/UgpuORtTCII/AAAAAAAAAts/H1A9ZgcdCiw/w763-h572-no/2013-08-13[/IMG] [/QUOTE]
