What rules does Spain shoot to?
Both the BFTA and the WFTF allow slings and the sling can be fixed in a one or ( maximum ) two postions on the rifle. The only difference I can see is that the BFTA insist the sling is 'attached' to the rifle at all times. Some shooters remove it from the attachment point and leave it dangling over the butt area, when not in use, and this seems fine. The WFTF allows the sling to be unclipped when not in use.
Useful ( a must ) for steadying prone shots but no one really shoots prone. Also useful if you shoot kneelers with the elbow close to the knee so that the upper and lower arm form a 'V'. In that case the sling will bridge across the top of that 'V' and can be used, as it's intended, to take the weight of the rifle, so the muscles of the upper and lower arm are not being stressed by the weight.
Most modern FT shooters have the elbow way back along the thigh with the fore arm resting along the thigh and the wrist slightly forward of the knee. In this style there is no real 'V' made by the upper and lower arm. So a sling attached to the rifle and the upper arm would basically just run along the forearm. It would do little to take the weight of the rifle as the weight of the rifle is supported by the fore arm along the thigh.
Some will say that a sling is useless in FT because targets are at different angles. If the shooter uses the more traditional elbow near knee stance as described above, it is easy to adapt this style for angles and still get an advantage from a sling ( you just adjust the point of contact on the upper arm ).
So most modern FT shooters dont use a sling.
