Adam,great shooting with a springer!
Here's my 8th and 9th official attempts, 3rd and 4th with <4 MOA groups, just not all in the 4 MOA circle. I'll get there soon. I'm very impressed with the rifle, not bad for a ~$350 springer (I bought it with the full tune from Flying Dragon). It's shooting the JSB Exact Jumbo Heavy 18.13 gr at ~755 FPS for ~23 FPE at the muzzle.
Where did you get the targets from? Would love to try that with either my liberty or Aspen.
