Crosman 160 tuning

[jirushi]

Thank you John.
I understand.
I'm a bit of a shot string geek; I stop counting shots when I think velocity drops too much.
If I would count whilst plinking, the number would be higher. A few cm's drop on an empty beer can "don't matter"!
Can't wait to do try the S331 peep sight outdoors. A bit chilly for CO2, but a sunny October weekend would be just right.

that's a good result Louis

I can picture you with your white tunic and shot string graphs and equations like a mad scientist. 50 consistent shots is very good for any co2 rifle, I've never thought to play around with hammer weights for adjusting power and economy.

Nice job on a very nice gun.

20 shots is crazy low. I get more than that on a 180, unmodified.

Was Rudy Merz the greatest airgun designer ever? I think there’s a strong argument for yes.

Agreed sir!

You missed out the best of the bunch the 180

The question is, what are your criteria for shot count?
I stop counting when velocity drops more than 10 m/s (roughly 30 ft/s).
The shot count was too low, for sure. But it's not that the gun was empty after 20 shots. For plinking, I could probably have kept shooting longer.
The Crosman 180 is more efficient out of the box. Except the early ones with a massive, single power hammer.
Power is lower compared with the 160. Mine do about 430 ft/s with 15.89 gr JSB. I should use lighter pellets in them, but I always test with one type to make comparing easier.

an SSG (google) will improve even further...
