Out of the curiosity of a few, and my own, I'll take on this task.
My relatively new (about 6 months old) Taipan, Veteran Compact, in .22 cal., I do not have any idea how long it sat on the shelf at the dealer.
I will take on the task of cocking, letting it sit for 7 days (+/- 3 hours), and shooting it. I'll keep track of all obvious parameters of the very lightly-scientific test.
One note - the sight was changed a while back. Just full disclosure !
Also, because it had not been shot in some time, I did put a few rounds through it before the test began, so the gauge needle is further off of the 3000psi. But, the tell, will be between the two photos that I will post.
1. I've topped off the cylinder. As verified with the 2" gauge on storage my air cylinder.
2. I put three shots through it. With the pellet speed as measured with my MagnetoSpeed, Ver.3., as measured in fps.
3. I cocked the gun (fourth round), putting a JSB, 18.1 gr. pellet into the breach, and put the safety "on". I never use the safety's !
4. I've put the gun behind the bedroom door, standing upright, barrel up, the barrel is lightly protected with a sock to keep rocks out. Only me and two cats live here, so no one will mess with the gun.
5. The gun will sit, undisturbed for 7 days, +/- about 3 or so hours.
6. Next Monday, after lunch, I'll verify the pressure in the guns cylinder.
7. I'll reinstall the Chronograph onto the barrel.
8. I'll shoot three rounds into my foam target, recording the three speeds in fps.
9. Will photograph the pressure gauge, both now and after the week is up.
We'll see what the outcome is, both in any obvious pressure loss from the gun, and in fps per the MagnetoSpeed chronograph.
Will write everything on paper and take a picture of it, so all can see my findings.
Have I missed anything ?
