There was this horsefly we had been tracking for over a mile, when suddenly, at 500 yards, we saw him zip out from the cover of a Griz he had latched on to, to throw off our tracking. My spotter followed him, miraculously, till he landed a just a bit further out on the wind swept terrain. The spotter then realized we were upwind of the Griz, who suddenly started leaping our way at about 35mph. We knew if we were to fill our horsefly tag that day, it was now or never.
Just then, the wind picked up, probably gale force strength I reckon, as branches on the far brush were being torn off from left to right. There I was, trying to line up the shot of my life while firmly holding my Barrett 50bmg off hand as best I could. I had my Niteforce 8-40X60 scope, that I got a great deal on from Aliexpress, zoomed in such that the fly was moving in and out view with each beat of my beat of my heart. But I was used to that and could time it perfectly as the fly swung across the reticle probably 100 times per minute. As good as that Aliexpress scope was, I'll admit the reticle was canted maybe 15 degrees, so the math was a bit tougher, especially with the 22LR bdc reticle. No matter, I have bagged dozens if not hundreds of horseflies using the same scope, albeit not at 500+ yards. This was to be the culmination of all my training and gear setup.
The fly was quartered to me so it was not as easy as it might first appear. Where to aim was the question. My spotter yelled out the Griz was closing in, that I had to take the shot, now or never. But in my mind, I calmly mulled over the strategy of putting him down, DRT, or taking a more conservative shoulder shot and having to follow the blood trail through the thick brush, with at least one Griz beelining our direction. Decisions.
I considered going high of the shoulder, for the spine shot, but then realized the fly has an exoskeleton, strategically thwarting hunters from taking that often successful shot. So as I peered through the somewhat foggy scope I dialed in the turrets for a head shot. That was the only answer to this situation, but could it be done?
With the sound of heavy breathing and grunting in the not too far distance, I lined up the shot, hoping against all that made sense, that the sound was emanating from my spotter. You have to have nerves of steel in such situations. My finger moved to take the safety off and just ever so slightly began to touch the trigger. It was a half pound trigger, so naturally the gun went right off that split second much to my surprise!
My spotter, who was sweating bullets himself by then, jumped almost peeing in his pants.
Luckily, and I know you might find it hard to believe, the blurred image of a fly flew past the reticle in that moment...just enough off center to make my calculated wind hold off just perfect, or so I hoped. As the bullet was in flight, we silently held our breath and crossed our fingers.
"Hit!!!" yelled my spotter. "You took the head clean off". There was horsefly blood everywhere, as it squirted from the torso, wings still flapping occasionally.
Was it an ethical shot? Well, maybe not. But that day, it worked out for my buddy and me. We had big smiles on our faces as we ran full speed from the brown monster hot on our trail. We would have to locate and field dress our quarry the following day, assuming wild animals didn't get to the carcass first. We slept well that night, let me tell you straight.
