Bayonet point of impact experiment
Posted: Sat Oct 22, 2011 11:20 am
Mikey_P, my friend Bob and myself were at the range yesterday for my annual Birthday Shoot. We conducted an experiment on the effect that a mounted bayonet would have on the point of impact (POI) versus point of aim (POA). Like yourselves, I had read and heard that the rifles were sighted in with the bayonet and the POI would be closer to the POA at reduced ranges.
The results are below. The results were shocking to us in person. Not only were the shots closer to POA the grouping was much tighter! The excellent Polish light ball and a like new 1943 Izhevsk 91/30 were used by my friend Bob to conduct the test. Unlike myself, Bob has excellent results shooting with the 91/30 open sights. The bayonet was chosen to fit very tightly yet still be easy to mount and dismount. I realise that this is only one rifle and particular bayonet with a certain type of ammunition conducted by one shooter in only one weather condition. Next time out I will try it with a different bayonet and rifle to see if similar results can be produced.
Edit: Forgot to add that five shots were fired at 100 yards for each group from a rest. One of the five from the "with bayonet" group was a called "flincher" the other four were grouped nicely in the circled area.
