I got out yesterday in the desert and got a chance to shoot my Bergara B-14 HMR (Hunting and Match Rifle) again. It was 43 degrees, barometric pressure was 30.32”,wind was variable out of the SSE between 6 to 12 mph and averaging 8.3 mph according to my Kestrel.
I first setup some targets. I setup a target stand with a paper target at 50 yards. I setup a 10” gong at 200 yards. I have some 10” x 10” square AR500 1/4” steel targets. The squares have a hole drilled in one corner. I picked up some Champion shepherd hook target hangers at Cabela’s. When you hang the square targets on the hooks they present as diamonds. I hung the square/diamond targets at 300, 400, and 500 yards.
I walked out to set the targets and lased back to my truck with my Bushnell CONX to confirm the ranges.
My muzzle brake and MGM Switchview Eagle Eye Lever had come in and I had mounted them on the HMR. I had also acquired 100 rounds of Hornady American Gunner 140 grain BTHP.
I measured the distance between the central axis of the bore and the central axis of the scope. With my setup it came out to be 2.0955”. I plugged 2.10” into the Nikon Spot On app, it will only go two decimal places, selected my Black X1000 6-24x50 IL X-MRAD and the Hornady American Gunner.
I selected a 50 yard target with a 300 yard zero. The app said that I needed to be 1.72” high at 50 yards to be on at 300 yards. I set up a 50 yard target and adjusted the strike of my rounds. I had a cloverleaf that 1.72” was pretty close to the middle of.
The targets were setup so that I was firing to the South. That gave me the wind from the about 10:30.
I fired at the 300 yard target and hit it with the first round a couple inches to the right of center. I held a little to the left and hit it dead center with the next two rounds.
On the 400 yard target I held up almost a mil since the Spot On app said that I would need a 0.85mil adjustment. I saw the strike of my first round to the right and behind the target. I continued to hold up and I also held to the left edge of the target and hit it with the next four rounds.
I tried holding up and left on the 500 yard target. I had a hard time with that and just barely missed all around the target with three rounds. At that range it’s a 2 MOA target. I looked at the Spot On Ballistic Chart and it called for a 1.8 mil up adjustment for 500 yards. It called for 17.3 inches of drift for a 10 mph wind at 500 yards.
I put on 18 clicks up and pushed 8 clicks left. I fired three rounds at the target with that setting.
I have some more learning and practicing to do but I’m pretty happy with those hits at 500 yards in a variable wind.
I think that my HMR is capable of better performance than I am at this point.
