• Matching a shell to a shotgun means finding the shell that gives the least variation in spread shot to shot. If the shell is known to give a repeatable spread, there is no need to 'over-choke' to guarantee pellet coverage in the centre of the pattern. A more open choke gives a wider pattern that can lead to higher scores!

• Detailed analysis can reveal that some shells don't give the coverage expected in the middle of the pattern - this can lead to misses even though the shooter is on the target.

• By using a digital camera image of a shot-shell pattern, Shotgun-Insight removes the tedium of hand counting pellet marks and allows patterns to be stored, analysed and compared.

Pattern analysis previously only available to the manufacturers is now available to you! 

Shotgun-Insight gives the shotgun user unprecedented insight into how shotguns and shells work together with a visual and numerical summary of shot performance.

• Find-out which shell offers the best repeatability in your gun.

• Evaluate the performance advantage of 'premium' over 'economy' shells.

• See the effects of long-chokes versus short chokes, back-boring, forcing cone profiles.

• Establish if the gun is under/over choked for a given distance and target.
