    Where theres a need is there a product ?

    This thread was an inspiration for me to take the old 760 out and see how hard it shoots with three BBs. 340-fps at five-pumps and 218 at three. What was interesting is that it shoots a tighter group 'shotgun style' than it does when you shoot the BBs individually. What the heck? It still...

    Different CO2 cartridges?

    ^ Thanks! I was wondering about that. Cheers, J~

    If you can find a Crosman 1100 Trap-Master it would do the job quite well. I had one with a sawed off barrel and it did a number on fruit-rats in the garage. Cheers, J~

    Low power tuning for Avenge-X

    You could probably bulk feed it co2. That would cut the max psi to around a thousand. I imagine that you'd have to mess with the regulator, though. Cheers, J~

    "If you find a bug-zapper and six-pack to be prime entertainment, well then... You might be a redneck." I'm right there with you. Three BBs loaded in a Crosman 760 pumped eight times works pretty well too. I'll chrono them when I get brave enough. Cheers, J~

    Low power tuning for Avenge-X

    Look up the Bstaley mod and see if that would apply to the Avenge-X. It's a buffer between the hammer and valve that reduces the impact enough to reduce gas flow and pellet velocity. It's worked wonders for my QB78. Cheers, J~

    Different CO2 cartridges?

    If they're labeled as containing twelve grams of co2, then they should be the same. Count the number of shots that the different brands give you at the same temperature. That should tell you if any are less than what's advertised. Edit - You could weigh them before and after use, as well. If...

    Crazy price of used guns

    After thinking on this for a bit... It seems that many people want to treat tools as commodities. A commodity is something that makes a company (or person) money (because if it doesn't, then they won't make money). A tool is something that is used to accomplish a task. My farm-think is...

    Crazy price of used guns

    I think it's reasonable that people want a return on their investment. I also think that most people aren't the technicians that they think they are and often do more damage than good. A look at just about any modified motorcycle on the market will demonstrate that fact. But... It gives us...

    Shooting bench NOT portable.

    It's looking good! Good on ya for putting it and a range together. We need more of both. Cheers, J~

    Grouping on blank paper

    Back in the day, I'd use a tripod mounted laser as a way to mark my point of aim. Set it, shoot a group, move the dot a little and then shoot another group. I eventually went to concentric circles made with a sharpie and a washer used as a stencil. Like this. You might try that to see if...

    Crosman 1968 Crosman 760 PowerMaster

    ^ That's cool! I had one many years ago. Found it at a flea market, fixed it, refinished the wood and gave it to my little brother. He kind of ruined it by replacing the receiver with a standard... I remember making the bolt knob on Dad's lathe. Cheers, J~
