Yes, 5 mm are still available by H&N in Germany. I have a couple tins of them that I ordered recently off of Amazon.
Any vintage pellet rifle enthusiasts out there?? Sheridan/Crosman

I have an heirloom Crosman 140. It’s fairly easy to change seals and put back in shooting condition. Parts other than seals are a treasure hunt. If anybody knows a source for the front sight I would be interested, even a cannibalized donor gun would do.
I have a Sheridan Blue Streak from the mid-50's. it still shoots hard and straight. I get the best accuracy with 4 pumps, to cover a quarter at 25'. 8-10 pumps are much less accurate, and may stress the parts too much.
The big old apple tree in the back yard was probably half lead by the time I left home.

An interesting (to me) bit of physics is that all pump up air rifles are pretty inefficient and don’t shoot as hard as we think. Most of the energy input with the pump is lost to heat of compression and warming the metal of the air chamber. One BTU of energy equals 778 ft-lbs of energy, far above the muzzle energy of any pump up pellet gun. Spring piston air rifles achieve much high velocities and energies as the compression and expansion is over in milliseconds before heat and energy is lost to the cylinder. I’ve never chronographed a pump up air rifle, but have read reports that velocities are in the 400 to 500 fps range, higher than the 300 fps that Daisy BB guns squeeze out, but nothing like the near sonic velocities of some springers or pre-charged pneumatics. That’s why all those vigorous extra pumps don’t accomplish a lot in a pumper. They’re still a lot of fun and every young boy’s lust object.
I have a Sheridan blue streak and it is as accurate and hard shooting as any I have had any experience with. I also have a couple of the old Benjamin 22 pistols that are fun. I have been working on the fundamentals of pistol shooting with a daisy 747 in the basement during the winter months. Air guns have their place in any shooters arsenal.

Sheridan 5mm's usually get around 11-12 ft lb of energy. That is 600 to 650 ft per second with 12 to 14 gr pellets. Doesn't sound like much but adequate for rabbits and quail!

I used to have one when I was a kid. They were the Cadillac of pump air pellet rifles back then. It's long gone to who knows where? But I still do have what I would consider the 2nd best of pump air rifles and that's an original Crosman 760 Power Master .177. All steel, brass bolt and wood stock with the wood 'Tootsie Roll' fore end. Circa 1964. Still works like new.

...are you still using the original Sheridan "Ashcan" pellets that came in the screw top tins or yellow box... If so get some H&N or Crossman Premier if you can find them...
Chrono results from some 5mms.... - 24hourcampfire
Love the Sheridans...still have several...

Of the two Crosman's that I ended up with, the Model 140 seems to hold air and work perfectly, but the Model 102 from the 1930's is due for a rebuild.
I just ordered a seal rebuild kit with the Crosman tool to do the job.

I own a couple of springer guns as well, here are my Beeman R1 (.22 Cal) which was built in 1998 and my Diana Model 45 (.177 Cal) which was built in 1987
I rarely shoot these, but they are pretty cool little guns!

Looks like one of the 140 Defender series models.

we have a winner ... it's a unique transitional model... overstamped model.. no parts get wasted at Daisy

If there is anyone interested, I decided to post my Sheridan BLUE STREAK up for sale here on the SWCA forum.....
Hoping someone will want it for themselves or perhaps a child or grandchild!!
