We received these charts from Huben to share with GK1 enthusiasts. These were shot using JSB .30 / 7.62mm Light 44.75-grain pellets.
The .30 Heavy also shoots well with it. We’ll look for a .30 slug that fits. Requirements: Not too heavy and with some extra length to accommodate the spacious magazines.
We still have a few left in stock due to cancellations. Take advantage of this offer! ;)
