with no more noise than a BB gun. This requires a laser rangefinder, and the use of both wings of the peep sight, a "see-thru" mount and a scope. But you can aim between his eyes and hit the brain, at any range closer than that.

what you do is zero the "normal range' wing of the peep sight at 50 yds. The 1000 fps, boattailed bullet will strike 2" high at 30 yds, but that's still a brain hit. :-) it will strike 2" low at 70 yds, but so what?

Zero the "long range" wing of the peep sight at 90 yds and the bullet will strike 2" high at 60 yds, and 2" low at 110 yds. So what? Still a brain hit.

zero the scope at 135 yds, and the bullet will strike 2" high at 100 yds, and 2" low at 150 yds.

The shots, thru a good silencer, are as quiet as a BB gun, and the bullet still has 800 fps left at 150 yds, which is 140 ft lbs. Plenty enough to put that pointed rifle bullet clean thru a head.
