Got an upgrade...
HW100 Carbine in .177. It arrived shooting 10.4gr AAs around 900fps and I turned it down a bit so it is now shooting 8.4gr AAs around 860fps.
Before
After
I just assembled and installed the tube so I have not had a chance to run a chrony string yet. Heck, I have had the rifle for over 3 months and hadn't ran a chrony string with the small tube.
BTW, the longer aluminum tube weighs less than the short factory steel tube.
