As some of you may have seen I've been playing around with my recently acquired 1866 44-40. First regulated the sights for 100 yds. by simply working the front sight down. With the ladder up and in its lowest position, the rifle shot close to a foot high at 200 yds., so some tedious work was required on the rear sight, but I got it. So just for grins I thought I'd see what it would do at 300 yds. In preparation yesterday evening, I calculated that the bullet would need to strike about 33" high at 100 yds., so I set up a target board on my 100 yd. backstop that would allow me to check the elevation. I started on the 300 yd. mark on the ladder and much to my surprise POI was just about perfect, striking only a few inches too high.
I then hastily moved my old 600 yd. target in 300 yds., cleaned and painted the old 36" gong and this morning got it all up and ready about the time the sun broke the horizon. The area in which I shoot my 100 and 200 yd. targets runs SW to NE which is just about perfect for our prevailing SW winds. But there's no room to shoot out to 300 from that position. So I have to shoot longer distances along my north fence which means I'm shooting to the west. This creates a couple of problems in that it's almost a requirement to shoot in the morning before the sun gets behind the target and before any wind gets up. Too I don't have a shooting bench so shooting from a prone position with a makeshift rest is the only option.
This morning there wasn't even a puff of a breeze...at first. I ran 10 or so rounds loaded with 9.5 grs. of Unique and the NOE bullet through to get the feel for it, then painted the target and tried again:
Certainly not match accuracy but pretty darned good for a stubby little lead bullet, I thought.
Emboldened, I hustled to the shop and threw together 20 rounds with 2.2cc of Swiss 3Fg and the same bullet. I got in three shots before the wind picked up, that'd be the three in the center of the five pictured below. After that, it was almost impossible to get any sort of accuracy because of the wind. To put it into perspective, the little bullet drifts about 3' at 300 yds. with a 90° 10 mph perpendicular cross wind.
Rifles such as these with so much drop in the comb of the stock are incredibly difficult to shoot with the barrel (sight) elevated because proper cheek weld on the stock is all but impossible. If/when I do this again I'll likely build up my sandbag test in order to get the rifle, and me, up off the ground a bit more.
I may, just for grins, someday drag the target out to 400 yds. and see what happens!
