Shooting Prone with a sling, a fading art

[RStewart]

I have done my share of strapping into a coat and shooting Across the Course and Prone at 600 yards with a service and match AR. I also shoot a .223 bolt in FTR. My persoanl observations are the sling makes you a better position/NPA/mechanics shooter and FTR teaches you to read the wind/mirage better. For those that may not know, the Prone X-ring at 600 yards is 6". The FTR X-ring is 3".
Many of the really good F-open and TR guys I have been around transitioned from prone. I highly recommend people trying it.
