Chrony test on 3 air guns, B-4-2As .
Proof of factory's oil dieseling.
Ok, here are the results of my
Chrony tests on 3 different air guns with different treatments. All 3 air guns
are B-4-2As and are .22 cal. I used Crosman Domed Pellets for the test. Each air
gun is new and has only 10 shots each on them. 2 of the air guns were treated 10
shots ago and one has no treatment what so ever, just as it came.

The first chrony results are from a B-4-2A using "Slick 50 Advance
formula" only.

From these tests I found that the un-treated air gun's factory oil dieseled
became thick/sticky and caused lost of power with only 21 shots (total: 26 shots), which is something I have known for the longest time and have stated it
time and time again. Notice the drop in power where I have placed 3 stars on the
fps number.
The best speeds (fps) came from the air gun that was treated with Slick 50 only.
I also found that the Slick 50/moly mixture gave the best consistency after 23
shots.
Well guys, I hope you all found the results interesting I sure did.
Sincerely,
Eddie Ferrer
