Crosman 600

[fullmetaljacket]

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.

A couple of things, firstly the cocking lever should be returned to the forward position before firing to avoid wear on the screw or slot in the hammer.

The late models had steel triggers and a button safety catch, replacing the serrated 'thumb slicer' unit as well as the push in piercer unit. Brass and alloy valve units were used.

The pistol in your video has no safety catch fitted.

Lots of these pistols had upgraded parts fitted if they were returned to Crosman service stations and latterly by owners switching parts.

Thanks for the very informative write up and video clips.
I do like the grips.

Thank you gents.

I'm aware of this faux pas, in my defense I was more concerned with the camera at the time.

That I did not know, thanks for pointing it out!

Almost certainly the greatest of all the great designs by the great Rudy Merz of Crosman. I had the opportunity of talking to Rudy's son and he told the story of how one day he was playing his accordion on the porch with his dad watching the mechanism and it was from one of the actions of the accordion that Rudy got the idea of the swing arm mechanism in the Crosman 600.

Everything about the 600 including every service manual, every owner's manual, every service station bulletin, recall notice, every piece of paper that Crosman ever published on the model 600.

Note: still have not been able to kill the Kindle edition. It's not good enough quality to read all of the graphics. Don't buy it.
