I spent some time yesterday doing some trial , and error tuning on my .22 cal Guantlet 2 SL , and wanted to share what I found with anyone else messing around with theirs.
First there is no need to adjust the belliview spring washer stack as there are 3 shims that are easy to get to , and as a matter of fact the stack is contained by a white O ring that holds it in place , so the configuration can't be messed up , or washers lost . I started by removing the 2 blue shims. That change alone had the Guantlet shooting 14.3 grain Crosman Premier HP really well.
Then I replaced 1 blue shims , and that had the rifle shooting the 16 grain with excellent accuracy. Next I tried removing the brown shim , and replaced the 2 blue shims. Even though the velocity wasn't at 890 fps accuracy was very impressive. The first pic is the Crosman Premier groups.
The second pic shows the last 2 groups 1 , and 2 with the 18 grain field , and target Apolo domed pellets. The last 2 pics show how the stack is not easily disturbed being held in place by the white O ring. This was very simple to do , and now that Guantlet does not have to be left shooting the 25.4 pellets only. Be careful with the 3 tiny screws holding the bottle cover on that was the hardest part. I was able to post pics the the "Guantlet regulator stack" post please see them there. Thanks OldVet. Today I got my eyes dilated, so asap I will use the hammer spring adjustment , and see if I can up the fps from 835 to a little more. Maybe my local Hardware will have some super thin shims , and I can one or more to reach that sweet 890 fps goal I have in mind. OV.
