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.
I find it’s easier to find the knowledge niche I’m looking to fill online. I like to skip to results, or watch the shooter’s position for clues, comparing to what I do. I find individuals on the range very specific to their chosen pursuit. Often I feel the span of shooters I watch online would not feel that the others had much to offer. F class, centerfire PRS, Rimfire PRS, Benchrest etc.
