Are there any videos and books that really go through proper shooting technique. Looking for material on proper form, grip on rifle, trigger control, breathing ect.. I find tidbits on youtube..sniperhide stuff but not one source. Id even be interested in hiring a pro instructor or take a class..Any leads? My shooting has improved alot over the past 2 years but still get flyers on groups and am sure I could get better with proper instruction. If I ever did enter a F-Class competition, Id like to not look like an ass
