Bill,
Go back to the Main Index ( There's a mall underlined heading at right top of every page). Then click on "Post" and you can start a new topic.
The reason you go back to the origonal post is probablly that the site thinks you're answering "that" post... Just always use the Main Index "Post
and your problem should cease, OK?
BBA#4 quotes the .177 Winchester 423 as being capable of 480fps. I have a Hy-Score variat, and can attest to that figure. Hard hitting little things!
I haven't really tested the Gamos for accuracy yet. The ones I did shoot, shot similar groups to a Crosman Point though. (The trajectory is about 30% flatter at 20 yards). Avoid letting the kids fool with these though, as potential richoets will be worse than with a steel BB. The additional edges of the Diabolo pellet shape could be even a worse safety hazard too.
HTH,
ZVP
