The latest addition to my stable and a classic that has been on my list for a long time.



The Crosman 600 is a CO2 powered pellet pistol manufactured between 1960 and 1970. Unlike its contemporaries it was equipped with a unique mechanism that used some of the gas from each shot to actuate a shuttle mechanism that took a 0.22" lead pellet from the inline magazine and placed it in line with the rifled barrel at the moment of firing.



This particular example is a late model denoted by the plunger on the chamber cap used to puncture the 12 gram CO2 cartridge that powered the pistol. The wooden grips are aftermarket items.



The magazine follower can be cocked back into a notch allowing the 10 round magazine to be filled from the front.



Fully loaded magazine.



In the fired position, the shuttle is in line with the barrel. Cocking the hammer puts it in line with the magazine, allowing a pellet to feed. Once the trigger is pulled, the hammer simultaneously opens the valve momentarily while putting the shuttle in line with the barrel. Full video: https://youtu.be/1F7M3_zdBQA



The mechanism is seen here filmed at 1000 frames per second. The CO2 which escapes the valve not only propels the pellet down the barrel but also recocks the hammer which in turn returns the shuttle to the magazine feed position.



There is no seal around the shuttle, so in spite of it being a tight fit a visible amount of CO2 escapes around it. The pistol fires 14.3 grain pellets at a respectable 335 feet per second, sufficient for backyard plinking and for dealing with small pests at close range.



Viewed from above, note how the stack of pellets in the magazine temporarily moves rearwards at the moment of firing, as the domed head on the next pellet in line is forced out of the hollow skirt of the pellet about to be fired.

Nice addition to your collection - a true classic!

Great review of one of my favourite pistols.
Nice touch with the cocking/firing video...

Thank you all for the kind words.

This is very important to keeping your 600 in good condition. Air will start leaking out the breech if the gun is not cocked when the co2 is installed, this will send cold air into your gun, drying out the seals and possibly destroying them.. I would add a drop of pell gun oil or hoppes lubricating oil on the tip of the co2 every time. My 600 was having issues untill i lubed the gun liberally and started putting oil om the tip of every co2, now she works flawless.

Great post PZAM, and hats off to rws for his contribution. Had one of these for a few years and loved it (except for its "as stated by rws," need for TLC with the feeding mechanism). Wadcutters work best in this pistol. Manufacturers today are getting pretty close to perfecting the semi-auto pellet feed. I'm hoping they'll keep at it, as its rareity suggests that there may not be a big market for BB-like feeding with pellets. I, for one, hope that it becomes the challenge to conquer in this generation of pellet shooters.

I was aware of this but naturally the only time I filmed it I neglected to do so



Cheers!
