bowket used to sleeve the 52 cylinder down to 25mm for 12 ft/lb guns, add weight to the piston for smoothness and increased efficency for a given spring(maybe not as relevent on a 54)and only enlarged the transfer port on .22 high power tunes, i think that was to get the ratios better matched 25mm:28mm and/or the pellet size 4.5mm:5.5mm
would a moly filled delrin sleeve be a possibility i wonder, although only 1.5mm thick sides and it might be difficult to get it to stay inside the piston
just a thought |
