Normally all the predators there got a free pass as they helped trim what was an enormous population of jacks (I shot up to 400 a night that year).
Must have been quite the long night, unless you were bagging ~1 per minute. Did you mean to say 40 a night?
Nope, up to 400 is not brag, just the facts. Spot light hunting doesn't take much of a marksman to do well when most are shot at less than 50 yards, many less than 25, and the longest there is normally only about 125 yards. So no, not brag on shooting. This is a large property planted 1/4 section center pivot in a checkerboard style surrounded by at least 50 miles of sagebrush in all directions. So its a beacon for all wildlife in the entire area and is literally over ran with many species after the Medicago, and those that feed on them. He normally gets 4 crops per season, but that year the jacks were in an all time high upswing. Between them, the GS's, pronghorn, deer, etc he lost about a third of his crop even with the thousands of jacks removed that season.
I could night hunt 8-12 hours a night depending on time of year, but I more commonly hunted 6-10, or until I got tired or cold. All "corners" and about 1/3 of the way into a field always had at least a few jacks first time visited, some up to a couple of dozen, and there were a lot of field corners (way over 100). Spots and headlights didn't spook them, they were use to farm vehicles daily and hay haulers at night. Nor did the 17 rimfires much if you worked them from closest to farthest. So a corner could score quite a few jacks in a very short time period - literally in a minute or up to 3-4 several to maybe up to 20 when I used my Marlin 17VS with 4 clips. Even after shooting a corner, a couple of hours later it would have a few jacks back at it again to shoot. So the entire night could be spent doing the two-tracks slowly around and between fields sweeping through the entire property end to end as many times as you wanted to. I had my 100 per and 200 per nights as well, those usually early and late in the year, or when I walked the property instead of driving and shooting from my truck, or for less hours total spent hunting. Why I said "up to 400 per". The night I shot that kitty was in October, very cold at that elevation that time of year and the jacks had been constantly weeded out all that season. Other than to first hunt there that spring (was too early in March) this was the lowest score that year at only 98 jacks total shot that night in about 6 hours. It was cold and I was tired from the cold, so called it a night and just hunted back in to the farm compound soon after I got the kitty around 2 AM. That particular kitty was the prime target that night anyway, so was mostly just shooting jacks while trying to find it.
