JSB Pellets have been developed over a long period of time and are considered one of the best on the market. The weight distribution from pellet to pellet is less than with many of the competitors and gives a constant speed.

Some JSB Pellets are made with sizes for example 4.51mm, 4.52mm or 5.52mm. An experienced shooter with a very accurate shotgun with an imposition will, in some cases, notice a difference between a 4.51mm or 4.52mm. If you shoot freehand or recreationally, you will not notice the difference between 4.5, 4.51 or 4.52mm
