I recently acquired a Gamo Whisper .177 air rifle. LOVE IT. Groups within 1.25" @ 20 yds. for me at the moment and I've only got 250 rounds through it. (at a price of 5.99 for 250, this I can afford and not be working at the moment)
My question is:
How long will the charge last if you crank it, load a pellet and let it sit waiting for Mr. Woodchuck to appear?
Anyone have any experience on this?
