I shot over 300 rounds between June and October and got my APS .300 Weatherby dialed in. To get the BC of the .210 SMK I shot through a chrony at 10 feet and put a second one at the target at 300 yards. This received some strange looks at the range, but I managed not to blast the instrument. The BC of the .210 grain SMK at my range is approximately .645. I fit the velocities from Exbal to the velocity measured at 300 yards. This BC worked where I practiced at 600 and 800 yard across local canyons at various elevations so I figured I was close.
I purchased this rifle for some long range elk hunting where we camp in the Beaverhead Mountains of Montana after watching bulls disappear into Idaho out of range year after year. That did not happen this year, but my first goal was to shoot an antelope out beyond 600 yards and I achieved that goal.
I hunt antelope just northwest of Glendive, MT. Some call it West Dakota. We meet at my friends shop and head north a mile. We are not in the middle of the second section when we see a buck and two doe, about a third of a mile off. I grab my stuff and climb through the grass to the edge of the field and set up.
The buck is at 647 yards and staring at me, this thing crawling off of the road. I check the drop from the print of the JBM Trajectory online output (yes, I left my PDA and Exbal at home) and give it 2.6 mils elevation. The wind is about 10 mph at 9'oclock so I give it about .5 mils windage. The pronghorn grazed about 5 to 10 more yards away from us then stood broadside. When I check where the crosshairs met from the .5 mil windage, I cringed at the picture of them square on the rump.
I squeeze one off as the sun is breaking the horizon and get back on the target as the bullet hits the buck and dirt kicks up in the pasture behind. It half reared up and fell over. It was the neatest thing seeing the bullet hit. My first thought was, "I am glad the wind did not change." My friends from out east there were cheering and one exclaimed he would not have believed it if he hand not of seen it. I know it is not super long range, but it is still pretty far.
I was told that I need to clean up my hands and some of the blood so that the picture is more presentable. I will do that next time, sorry.
