My pellet probe on my impact seems to be out of line. The screw holing it is tight, but it is still wobbly and not going directly in. Is there another screw that can tighten it up so it wont move so much?
That 3mm screw/hole keeps the probe in given distance only and shall not expect other function from it.
The co-linear alignment is a stack up tolerance in between the probe OD and holding block hole ID. I don't see other way to tighten the co=linear only to shim it or make a new probe.
The other possibility is that the block (feeding pin holder B10) got loose on the loading mechanizam assy (feeding pin guide - B12)?
Btw, mind you sharing how did you got there a pin to be loose/not alligning?
Speaking of the probe and THAT screw, I just had to order another probe assembly because I stripped ANOTHER screw trying to remove it. I'm 2 for 2 having to replace the assembly. Like Yo said, it must be red locktite. There has to be a better solution, perhaps using star shaped torx screws???? Tried heating with heat gun still no go, kinda important with the Impact being a caliber changing gun!
So THATS WHY they use RED LOCKTITE? Try turning the gun UPSIDE DOWN see if that helps.
