Terrible Marksmanship principles

.
these old rifles required good marksmanship principles but modern rifles are easier to use.
Indeed the old SLR Rifle we had in the 80s was much different to the later Sa 80 rifle.
The SLR was a rifle that packed a punch but you needed to know how to use it properly, the Sa 80 was ( i only used the first version) much easier to shoot and average shots were suddenly hitting every target.
That Kid didn´t know what he was doing with that rifle & he was walking around openly so zero experience in a built up area... he was a fool.
