I'm in the process of making a new CF shroud system for my .25 Wildcat and Impact. Does anyone have info or a good link to info regarding air stripper bore diameter, and distance from the muzzle. I realize this may be hard earned info that somebody doesn't want to readily give up but it would save me a lot of time If I had some good "start point" references. If I figure out how to post pics here I'll publish the projects when I get them well under way; just got an email the CF tube I ordered is back ordered until the end of the month, so this will be slow and painful. Much thanks!

Seeking air stripper info
- Thread starter sgtskinny

When I built my air stripper (no shroud), I chose the gap to be the bore diameter long. The diameter of the stripper for a caliber .177" is .225". The cone is 45 degrees included angle and creates a sharp edge. I have six vents (5/32" x 1/2") that give a total gap area of .469 square inches.
This is by no means the only approach. Many are right angles to the bore with round vent holes.

ILI, thanks. My first prototype for the .25 has a bore of .277" ( "I" drill ), slightly tighter than OEM, my thought was tighter should be better, to a point, but only experimentation will tell that tale, I can modify or build another stripper insert if it turns out to be too tight. I built an arbor to snugly fit the rifled section in the muzzle to verify everything is in alignment, so far all is fitting well, taking my time and doing the most precise work my equipment will allow. Muzzle distance is adjustable out to 1", but I planned on starting at about .375" . Not a lot of detailed info out there that I can find, must be one those well kept secrets because its not a new concept.

I was able to shoot a few mags today. I tested the stripper/muzzle distance at 3/8, 7/16, and 1/2, so far 1/2" produced the best group. Way to early to draw any conclusions, but its already shooting better than the OEM stripper so the preliminary results are encouraging and at least now I know that my stripper bore isn't too small, I may even try smaller.
