At 8 the average Streak is just about the same, maybe a little higher. I asked that question of Streak owners this year on another forum, low to mid 600s

That’s why it will be fascinating to see what your new one will do with a reseal. I’m betting your surprised, it looks to be pretty much untouched? I don’t think I’ve ever seen Chrony numbers for a .177.
Hi 45flint, that's very interesting thank you. I just had some time to test both my T&C 108 and Blue Streak.
Per number of pumps I took the average velocity of 3 shots.
Here are the results (I can't get the layout right, excuse me):

T&C 108. .22 JSB Exact Diabolo Jumbo Express 14.35 gr
Pumps. FPS ft/lbs
3. 305 3
6. 460 6.7
8. 525 8.8

Blue Streak. .20 JSB Exact Diabolo 13,75 gr
Pumps. FPS ft/lbs
3. 427 5.6
6. 512 8
8. 551 9.3

Both airguns have been professionally resealed within the last 4 months.
Perhaps the T&C prefers the Crosman Premiers that you are using? They might fit better in the barrel?
I'll have to do some testing with different pellets.

The Crosman is a lot quieter at 8 pumps compared with the Sheridan at 8 pumps. Yes, the Sheridan produces more power, but it is way louder. And way harder to pump.
I like them both though!
Can't wait to see what the 107 does.
