Dag Evert's "American Classic"

As mentioned on the forum, heres a picture I took some time back, with natural winter daylight.
A 2100, and a 1377, both guns have been recrowned, and had their trigger parts shimmed for play,
contact surfaces stoned, and trigger springs somewhat reduced within safe limits.
The 2100 has had its barrel shimmed with tape to remove play.
Both guns give great accuracy for the money if they are given good pellets!
The combination of pellets and guns in the picture represents something close to my boyhood dreams:-)

Response to Ok, here's some numbers, this is maxed out,

........especially in .177. Performance is remarkable - hows the cocking effort?

Update:

I read your post on the yellow (can't post there yet). Thats cutting edge stuff for sure.

I think what we're looking at is....FT = MV. Since the valve is low volume then time is not your friend. To max out V for any given M, F or transfer pressure becomes critical. It looks like you've hit a near perfect balance between the compromise of flow rate and transfer volume. Also, the heavy's should outperform (fpe) because of two reasons. A slower acceleration due to higher mass will give the FT side a boost by allowing the force to stay higher for a longer time; also, there is always less energy loss with lower velocities. Going forward, I wouldn't know how to improve (efficiency) if you've already eliminated or minimized all transitions (size, shape, direction) in the transfer.

Awesome!
