Last month I helped a friend set up his Browning A-Bolt in 30-06 with the Federal 165 gr Sierra GameKing BTSP with a new VX3 3.5-10x40 with CDS. I clocked 10 rounds over my Oehler 35p @ 2811 fps average. It took Leupold about 3 weeks to get the new CDS turret out to him. I helped him zero the scope @ 200 yds and we then checked the POI out to 600 yds in 100 yd increments. All were a few inches low but that was to be expected since were shooting at a nominal 4900' elev and the denser air would slow the bullet down more. He had an elk hunt to the Windriver range of Wyoming with a 10,000' average hunting altitude of which he just returned from yesterday. He texted me this pic upon arrival at his house. This is his 7 yr old son in the back of his Toyota Tacoma.
Seems the range was 456 yds, one shot at a slight 5 deg down angle. POI was right at the POA after he turned the CDS turret upto the 450 mark. Bull only traveled 10 yds. Autopsy showed a clean double lung hit with several largish exit holes on the opposite rib cage.
Also, I had Leupold make up three turrets for my Pre 64 M70 in 9.3x62 with a VX3 1.75-6. One for 500' (Seward Peninsula), one for 5500' (primary year round practice) and 10,500' for elk hunting. It works great out to 500 yds.
