If I buy rounds for Longarm or Sniper (charges/cartridges 25) for a weapon with a capacity of 2 rounds (Tactical Shobhad Horizon Striker), then is it 25 cartridges = 50 shots? Or do I only get 25 shots from that?
It means it has 25 bullets in the pack. Your Horizon striker can hold two bullets on its own, and fires 1 bullet each time. That's 12 full reloads and 1 bullet left over. But only 25 shots.
