I never even thought to research instructional videos.
I watch youtube videos routinely for reloading, but never crossed my mind to watch shooting videos.
That being said though, the best instruction I can possibly get is by attending matches at Nokomis and learning from other, more experienced shooters while I am shooting at the range.
Especially true when the F TR guys from Alberta come and school us local guys.... when they choose to share information, I listen very carefully
There will never be a substitute for trigger time.... especially on days with gusts and/or changing directions.
