Quote from: Wayne52 on January 25, 2022, 03:33:43 AMI installed the Alchemy Werks extended probe, it's velocity is less than the stock probe that came with it was, about 20fps slower at 8 pumps. I do really like the magnet on it though.The velocity change may not be due to the probe shape, but by the length of the rear end slightly interfering with the full forward travel of the hammer/cocking pin on firing. Check the back end and see if you are seeing excessive peening from the pin.Secondly, do the tissue test to be sure the probe o-ring is sealing to the barrel with both probes.

This is with a totally factory setup. I have a Baker aluminum breech on the way, so I'll find out if the included probe setup works. I'll look for peening like you mentioned. If there is some contact, should I just file down the back of the probe until it stops?
Some chony numbers with 14.3 grain crosman premier hp. 5-shot averages4 pumps = 514 fps (8.4 ft/lbs)5 pumps = 563 fps (10 ft/lbs)6 pumps = 599 fps (11.4 ft/lbs)7 pumps = 628 fps (12.5 ft/lbs)8 pumps = 658 fps (13.75 ft/lbs) well thank you i know my cheap chinese chrony is working thats the same numbers within 10 fps one way or other same pellets 10 pumps = 701 fps (15.6 ft/lbs) my 362 is getting
Hopefully will receive my new 362 tomorrow…very excited to join this highly exclusive club! Is there a password or secret handshake?I spent a very productive day at work today reading through this whole thread. Lot’s of good stuff going on here.

If there is some contact, should I just file down the back of the probe until it stops? Yes, file or turn it down til the pin no longer makes contact. I found that a bolt popping up on the shot is a sign that the pin is hitting the back of the probe. Usually seen in guns that are over-sprung on the hammer spring ... as I suspect the C362 is.As a matter of fact, I face almost all 22xx bolts a bit as not only does it remove the chance the hammer pin will smack it, but it also offers a bit more space for the loading of a pellet in the trough. However ... take too much off the back end and the gun won't cock.
AIr Venturi come out with a nice pumper as well. The Seneca Dragonfly MK2. Wonder how it will compare to this one?
I had a couple of sessions up in the attic with mine today shooting my lucky 13 target, here's the second one that I didn't publish but left it unlisted, the first clip normal speed and the second clip is 4X speed
Anyone tried fitting the 362 mechanism into a 2260 wood stock?
