If you observe the video, you might catch the wind noise from the camera's microphone. Also, if you watch the target, it moves in and out with the wind force.
The shooter was not facing a calm day for his shooting. You'll notice on the fourth and fifth shot, he had to bring the revolver down more than once. He is affected by the wind, and this makes it difficult to hold the gun perfectly still and retain sight picture. He also has something else. He's being recorded on "film".
A match shooter knows he/she should not hold the gun on target more than about eight seconds. However, there is the tendency for a competitor to hold the gun on target until the shot is fired. I call it the "marathon fault". After 8 or 9 seconds of holding, accuracy tends to suffer and the barrel begins to waver, yet the shooter is going to hold the gun up until the shot is fired.
The other thing to remember in this video is the target. This is the 50 meter ISSF target that is normally fired in black powder revolver matches at 25 yards in the U.S. and 25 meters outside the U.S. Note the black "bull" is larger because it is designed to be shot at 50 meters.
The International Target has no "X-ring". If you compare this target with the NMLRA 25 yd Pistol Target, you'll see the disadvantages of the International Target. The black bull is too large to shoot at 25yds, when one "grew up" shooting a black bull measuring 5-1/2".
Black Bull area diameter
25 yd NMLRA Target: 5-1/2"
50 M. Internat Target: 7-1/4"
10-Ring diameter
25 yd NMLRA Target: 3-3/8"
50 M Internat. Target: 1-3/4"
All in all, pretty good for a windy day of shooting. If one were to transpose the hits onto the 25 yd NMLRA Pistol Target, it would likely score a 59-2X/60. To further understand the difference between the two targets, the 9-Ring on the International Target @ 3-1/2" is about the same diameter as the 10-Ring on the NMLRA Pistol Target @ 3-3/8".
What this boils down to is the competitor who is used to shooting "tens" on the NMLRA target will see themselves getting "nines" on the International target, which means trying harder to get "tens" in a circle as big as the X-Ring on the NMLRA target. The International target IS a challenge to shoot, especially to "Ace It", all tens.
When I shot at Friendship at NMLRA National Matches from 1987 till 1998, the International target is shot in both the Open & Traditonal Revolver Aggregates.
In one 30 minute relay, the competitor is allowed to shoot a maximum of 13 shots with the 10 highest scoring hits to count. 10 10's= 100 points.
In the late '80's, I brought along a fairly good pistol shot from Burlinton, NC to shoot for a week at the National Matches at Friendship. In the Open Revolver Aggregate, I witnessed him shooting the International event. With his Ruger Old Army, he shot 3 "eights" at 12:00. He adjusted his sights, looked at the time clock, bore down, and proceeded to shoot ten shots all inside that 1-3/4" diameter, 10-Ring, shooting a perfect 100 score (remember 10 highest count).
He won the National Championship that year, and his name is in the Record Book as the first to shoot a "100" score in the history of the Revolver Aggregate. John Rooker is also a "Distinguished Master" one of four from NC.
A "D.M." has to shoot at the National Matches, a 925 score out of a possible 1000 points (10 target events), three years, not consecutively. That means averaging a score of 93 on ten targets of which three targets are at 50 yards. Three pistols are used. caplock s/s, flint s/s, & revolver. And of course, one hand hold on the gun.
Quite a few people asked me not to bring him back the next year. He had so much fun, he came back for six more years. :banghead:
