Crosman 150 - Ted Williams, 22 cal 13.73 Pellets, same Co2 batch, Same chrony, same light source, same high power setting.

In April basement being only +10C

Shot count: 35
Low: 339
Hi: 382
Avg: 364
STD Dev: 12.5
Spread: 43.0

Same gun, same batch of Co2, Same pellets.

Today at+22.6 degrees.

Shot count: 34
Low: 325
Hi: 424
Avg: 396
STD Dev: 24.3
Spread: 99.0

It dropped hard at the 30th shot, From 372, to 360, 353, 336, 325

I never tried a shot string on the low setting.


The Cr150-TW Edition is a slick air pistol! What are the numbers like if you cut off at 29 shots (at 22 degrees)? It's looking like you run out of fluid CO2 at that point. I'm curious about the low number for shot 28 and 29.


Gotta love FX Chrony app.

It dropped hard after shot 30, so the low numbers were 31, 32, 33, 34..

So at 22 degrees, it shot well up to 30 shots. If I cut it off at #29. The spread would been cut in 1/2

Thinking of swapping the adjustable trigger and sear that I have in 2289, into the 150, and a trigger shoe may be a better upgrade.

Your first 20 shots look great with an average somewhere around 415fps for 5.25FPE. Then you get a little drop at shot #21 but your still good for another 9 shots at a slightly lower velocity. There likely isn't any CO2 liquid left at this point so it crashes at shot #30 onward.

The Cr150 only has a 6" barrel so 415fps at 22*C is quite nice.

I could probably have shot slower. It's quite humid here and the gun was sweating. But was shooting about every 10 -15 seconds. Probably go out later, and run a string on low setting. Got to love the 2 stage hammer.

I would recommend the CR 150 TW. Paid around 100$, full metal sights, 2 stage hammer ( Low/High ) Just needs a better trigger.

This was with the Stoeger 13.73 Wadcutter 22cal pellets. Same conditions as yesterday, same batch of ( Crosman ) Co2, same pellets range etc etc.

I had about 5 that did not register, in the early/mid shot string. So I would throw out that 378 last shot, and I bet it would be around 387. I bet the spread would be around 15 FPS.....

That's an impressive shot string for a single bulb and it still has decent velocity with the low power setting. Very consistent. You would likely hit 400fps at low power with the RWS Hobby. Not sure if your Cr150 likes Hobby pellets. Nice pistol!

Yeah I was very impressed at a Co2 gun, that isn't regulated. That velocity be good for paper punching @ 8m ( Basement range ) I got heavier hitting airguns if need them. Good thing about airguns. You got more than just one. Been working on the lighting in the basement to do better target shooting. Its been in the mid/high 20s, with high humidity, so it is unpleasant to be shooting outside.

I got many ranges lol.. Basement, backyard, backyard long ( when neighbors are out ) and a BB gun range.
