Nielsen HPDB 4.52 mm (.178) 12.5 grain Airgun Slugs

Nielsen 4.5 mm HPDB 12.5 grain (.178) airgun slugs are cold swaged in a hydraulic press. This process guarantees absolute uniformity in weight, size and shape, resulting in extreme precision.

The hollow point, combined with a soft grade of lead, provides an excellent expansion. Thanks to its bullet shape with dish base, the Nielsen 4.5 mm HPDB 12.5 grain (.178) airgun slug has a ballistic coefficient of 0.070. The slug has a length of .234" (5.9 mm).
