The rifle: Chinese Type 56 SKS (with bayonet extended, of course). The ammunition: Golden Tiger, 124 grain, FMJ BT. Regular iron sights; no scope or optic.
All of the targets, unless noted, were shot off of a bench-rest (crude, but effective):
On the first set of targets, I was using a 6:00 POA, and I tried to touch the top of the front post to the barrel on the target:
The distance between the center points of the two groups was approximately 2”, and both were below the POA.
On the second set of targets, I used a 6:00 POA and I tried to touch the top of the front post to the bottom of the 3” red square:
The center point of the BZ rear sight group was about 2-1/2” above the center point of the 100m rear sight group.
On the third set of targets, I used a 6:00 POA and I tried to touch the top of the front post to the bottom of the paper:
I fired five rounds using the 100m rear sights and none of the rounds hit the paper (low, I’m assuming). So, I switched to a center/just below center POA and got three out of four shots on the paper. I went back to the 6:00 POA with the BZ rear sight and got four out of five shots on the paper about 7” above the POA.
I switched to a shooting-with-my-elbows-on-the-bench (unsupported?) position with the “bad guy” target:
The POA with the 100m rear sight was a 6:00 hold on the center/upper center of the target. I fired six rounds. The POA with the BZ rear sight was a 6:00 hold on the center of the target. I fired 10 rounds. The distance between the center points of the two groups was approximately 8”.
On the last target I went back to the bench-rest and a 6:00 POA, with the top of the post touching the bottom of the target:
Ten rounds fired; nine on the paper and eight on the target.
Conclusion: One of these days I hope to be able to try the rear-sight meter positions at confirmed metric distances. In the meantime, I think I’ll work on getting proficient with both the BZ rear sight (out to 300 yds) and the meter notches at the corresponding yardage distances.
