What accuracy is possible with an airgun? August 16, 2008 As the range increases, so does the group size for all airguns. At 50 yards, a 10-meter target rifle will be shooting a group of three-quarters of an inch to one inch, while a top-quality sporting rifle like the AirForce Talon SS can shoot a half-inch [...]

At the same 10-meter distance, a nice sporter air pistol like the Webley Tempest or Weihrauch HW 75M will group five shots in one-tenth of an inch. A high-quality CO2 pistol like a Smith & Wesson 586 might group five shots in three-quarters of an inch and a low-cost CO2 gun like a Gamo P23 [...]

How to measure a shot group: August 11, 2008
You can measure the distance across the group with a common ruler marked in sixteenths of an inch or you can use a dial caliper that indicates thousandths of an inch. Whatever you choose, don’t kid yourself that a more precise measuring tool will make your measurements more accurate. This is a common mistake. Simply [...]

How to measure a shot group: August 10, 2008
When you measure the group spread, don’t forget that most bullets except wadcutters will tear raggedly through paper instead of cutting a clean hole. You need to find the true edge of the two widest holes. In the beginning it helps to stick a pellet in the holes to visualize where the edges are. With [...]

How to measure a shot group: August 8, 2008
Measure a group by measuring the distance from the far edges of the two widest shots, and then subtract one bullet diameter to get the distance between the centers. If the two widest shots of a group of .22-caliber shots measures 1.220″ across their widest distance, the c-t-c distance is 1.0″. The math is simple, [...]

How to measure a shot group: August 3, 2008
Measuring a shot group is not hard, but there are some things you need to know. The most common way of stating the size of a shot group is the distance between the centers of the two shots farthest apart. This is often shortened to the expression “center-to-center,” or “c-t-c.”…. Dirt E. Harry [...]

How to measure a shot group: July 30, 2008
If we’re going to talk about accuracy, we have to use some easily understood means of comparing relative shot placement. Shot-group size is by far the most popular way to do this. Incidentally, the term “group” is correct; it is not a pattern. A pattern is the spread of shot from a shotgun; a group [...]

What should you expect? July 29, 2008
A scope sight will make it easier to shoot any airgun more accurately, but it will not make the gun more accurate. Use a scope if it helps you shoot the gun the way you want to shoot, such as for long-range precision shooting and hunting, but also consider if other kinds of sights might [...]

The powerplant adds a small amount of additional potential, but that may become increasingly important with some kinds of powerplants if the shooter does not practice proper shooting techniques. Some powerplants, like those using compressed air, are very forgiving while others, namely spring guns, are not…. Dirt E. Harry [...]

What should you expect? July 27, 2008
Every product has specifications that limit performance. The barrel, powerplant and pellet are at the heart of every airgun’s accuracy. Other factors such as how controllable the trigger is and how well the stock fits the shooter are also important, but the barrel and pellet comprise about 90 percent of the accuracy potential for an [...]
