WildCat .25

i just dry fired my 25 cal WC MK11 and there was no puff of air from the breech i could detect. i fired with magazine removed.

Hey Crusher, what works for me in all my guns is high temp vacuum seal grease... it's thick, fills in any variation in the machined breech groove and lasts forever. No more puff, increased fps, seals last forever..... I use it on all of them

Hi Crusher, other place to look at;

1. The barrel set screw seats in between the 2 oring on the brass TP at time i seen screws that blow air even if its tight so I plying thread sealer or Teflon tape.

2. The pellet probe has a mill slot at 1 o clock that is vary close to the probe oring in the barrel when close, so if the pellet pobe depth at the rear of action is less then 28.50mm the probe oring could be seating on the mill slot then it will blow air at the rear.
