LFWA recently ran a 2-week gun camp/ tryout for our CFSAC team.
Now, I've never considered myself a poor shot, but my marksmanship increased exponentially in that 2-week period. I learned so very much, and a lot of it was little things that never really get covered in the standard SA ranges/classes.
We spent whole classes learning how to properly adjust the C79 scope, and then did a walkback, sighting in and adjusting at the 100m-500M. We spent an entire afternoon shooting only from the 500. I never thought I'd be able to hit that kind of grouping from that range with a C7. Because we just don't do it.
Snap shooting, shooting on the move, barricade shooting, etc.
Granted, a lot of what we did (about 1/3rd to half) was competition/olympic style matches, while the rest was standard ranges and firing positions, to CQB/gunfighter style shooting.
All in all, it was probably the best learning environment I've had when it came to SA.
Lot's of: "We're going to show you small things, if it works for you great, if it doesn't, try something new." and very little "Don't rest your mag on the ground! Because that's how we were taught"
There were a lot of basic principles that were better explained, and it also helped that we had enough rounds to try different things to find what worked for individuals.
