The Veteran makes a great low power .177.
The original Veterans were offered in .177 as a factory option. I've seen a few of the .177 Shorts, but it seems like many more .177 Standards were made. The Vet Short is about a 24" gun, and the Standard is around 28" long.
My .177 was originally a .22 but was converted to .177 by using a .177 CZ barrel from the CZ200 series guns. The Taipan OEM reg that was in the gun was not very consistent in the conversion so my .177 Vet has a HUMA regulator in it. My frankenVet also has a custom smaller transfer port, single hole and appropriate for .177. This was b/c the large dual transfer port from the .22 was also creating consistency problems. So I certainly went about getting a .177 Veteran the hard way, but it was worth it as it is extremely accurate. Reg pressure is 90bar. Shoots the 10.34s just shy of 20fpe. I'd estimate the shot count is up around 140-160shots per fill. And it is VERY quiet.
If in the market for a .177 Veteran at this point, I'd recommend you keep an eye on the classifieds, or even post a WTB and be VERY careful with vetting the responders before you send them any funds. (Personal experience is that WTBs bring scammers out of the woodwork, much more than a WTS).
