Good video, and that is how it is done here, insulation tape over the end of the barrel, bipod nowadays, plenty of blood over the clothes from carrying your own meat out. Good East Coast or Southland hunting country.
That is the classic high shoulder or brisket shot if the animal was facing, not the low lung heart where so many aim and then the animals runs. Okay in that open country but not in steep mountain or bush country.
Some nice chamois too.
