You don't know what you're talking about. This is field target. Almost all high level FT competition shooters use 10-50x60 scopes (some even use 80x scopes. The world field target rules are that you must use a sub 12 foot pound airgun, almost exclusively .177, and you aren't allowed range finding equipment, and aren't allowed to know beforehand what the distance to the target is. Knowing the distance, especially with the furthest range targets, is absolutely critical to making the shot because of the very steep trajectory of the pellet. The 50x scopes are combined with a very large side focus wheel, which is used to range the target. Very high magnification means very narrow depth of field. The scope is focused in on known distances, and the side wheel is marked for that distance. These scopes, when set up correctly by an experienced shooter, can be accurate to with half a metre, but temperature can throw them off. Some shooters use multiple marks for different temperatures. The bigger the wheel, the better within reason. This is because the distance markings are not linear, they get closer and closer together as the distance increases, a small sidewheel doesn't work past a certain distance because the markings get so close together that they become useless. This is a very specialised shooting sport, and the gear reflects that. This guy has probably spent upwards of $10K on his rig, and everything has been selected for a reason.
