    Crosman Powermaster 66 question

    Hey do any of y’all have experience with a Crosman Powermaster 66? Having issues with mine that I didn’t have in the past. I can pump it but it doesn’t shoot anything and wonder if my bolt isn’t closing all the way causing this.

    Where yat Boss. I don't have any experience with the crossman but I had a few that the seals needed to be oiled. When they dried out BBs fall out when shot. Looks like an old cartoon.

    What’s happening brother??!! This is a gun my dad had bought many years ago. I used last year to eliminate some pest birds and worked fine. Had a rat in my garage and tried to put a cap in his ass and nothing came out. No pneumatic sounds or anything. Might get a new o ring set and see what happens.

    is there resistance in the pumping? does it feel like you are building pressure?
    can you pump 2x fast and pull the trigger, see if there is action?

    most common cause of pressure loss is bad/dry seals/washers/gaskets.

    Hey Troy thanks for the response! I do feel resistance when pumping but it doesn’t seem to get harder the more I pump it. I will try the 2x pump and pull the trigger. What is that telling us?

    A Rat motor in your garage! Brake out the Mauser. How about .22CB caps in a rifle. Just take the Boss out first.

    if it fires after 2 quick, then its pumping, but loosing pressure.
    if it doesn't fire it is not "storing" the pressure it makes when it is pumped.

    if it feels the same each pump, where previously it increased, it sounds like the check/one way valve may be damaged or need lubricated.

    Ok I will try the 2 pump fire but it sounds like what you are describing in that the pumps feel the same each time no matter how many pumps I do and seems to not have any pressure stored. I will have to find out where this valve is and take a look at it.

    Ok so replaced the o rings and cup. Still not putting anything out the barrel. Starting to think it’s a hard parts issue of some type..about to put it on eBay for parts if I can’t get it figured out��
