One thing that most have overlooked was the origins of F and FTR shooting. It was created to keep shooters in the game.
As the sport is getting older, the sling shooting crowd has been dwindling due to age and eyesight. It takes a lot of time and physical effort to learn to shoot prone with irons and a sling. Eyesight is a very critical element in that game.
With the overall age of the prone sling shooters growing, something was needed to keep competitors shooting. Tubb many have actually been the catalyst for this with his scoped XC events at Perry. So lets allow scopes and rests to hold the rifles up in prone competitions. Basically it becomes benchrest shooting laying on the ground. High power scopes and rests dictated a smaller target. That was only appropriate.
So as I see it, F and FTR becomes a game of high quality ammo, an accurate rifle up to the wt. limits, repeatable hi power scope, good rests, and the ability to read the wind. The demand on eyesight is reduced with the use of scopes and rests and bi-pods reduce the physical strain of holding while aiming the rifle.
Sling shooting is high quality ammo, excellent iron sights, an accurate rifle, the ability to hold that rifle in position for 22-30 min (MR or LR shootng), and the ability to see the target thru those sights, and holding the rifle steady while breaking the shot.
The size of the target makes little difference as the sighting and rifle support system dictates that difference.
So the sling shooters have a more difficult time with the support and sighting system, the F and Ftr shooters are challenged with a smaller X ring. It is still a game of 10s and Xs no matter which game you play.
Enjoy it and go compete knowing that there is always a game that allows you to compete and enjoy a match with your friends.
Which is harder? That is the discussion over pizza and beer once the match is over
