there is a lot of good advice on scopes in this article: https://www.firearmsnews.com/editorial/modern-3-gun-scopes/326552
and here is how people shoot:
1-4x or 1-6x is plenty out to 500 yds. if you zero at 200 yds you can hit anyone from the neck to the dick out to 350 yds.
You can see from the vid: Rds/irons for short range quick acquisition (canted rds to the side of an optic).
Also I need that mag fed shotgun in my life.
Surprised that they let him unsling his rifle with the muzzle pointing backwards without giving him a DQ
