The JSB Knockout Slugs in .177 calibre (4.51mm) are hollow-point soft-lead slugs designed for use in PCP air rifles, offering a meaningful step up from conventional domed pellets for pest control and hunting. Manufactured by JSB Match Diabolo in the Czech Republic, each slug is individually selected from the best production batches, then weight-sorted to a tolerance of just +0.001g — a level of consistency that translates directly into tighter groups downrange. The hollow-point nose aids reliable energy transfer on impact. At 10.03 grains, this slug sits in a useful mid-weight bracket for .177 rifles, giving a flatter trajectory than heavier options while retaining more energy than lighter domed pellets. Supplied in a tin of 500, they are packaged individually to protect each slug during transport and prevent deformation before shooting. Best paired with a high-powered, regulated PCP air rifle with a rifled barrel suited to slugs.
