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 2240 valve mods

If I was you, I'd order a 1760 barrel from Crosman ( #1760-001 quoted $12.08 today ) which is a 24 inch .177 barrel, then cut and crown 1/2 inch at a time until you see a decrease in average velocity, then stop.

Make sure your bolt probe is long enough so that the pellet skirt completely clears the transfer port, but no longer. ( IMHO )

Any valve mod is likely to increase CO2 usage, but there are mods you can do to reduce it. ( at expense of velocity/power )

With your criteria of not increasing CO2 usage, I'm pretty sure there's not much else you can do.
