Ever had a weird POI change?
« on: June 21, 2010, 07:39:29 PM »
My RWS 350 will sometimes just change POIs.  It shoots just fine and then the next day it is off by a lot.  I don't know what may be causing the issue.  

I can adjust it pretty quick and get it back to its usual tight grouped self.  The way it is cocking the spring may be starting to give way.  It sometimes has a "hitch" when I cock the rifle.  Meaning it is smooth then kinda catches.  

My TF 89 is just the opposite!  I can shoot it almost anytime and it hits the same.  It has a home lube tune though and the RWS 350 hasn't ever had any work done on it.  Should I just go ahead and order a new spring for the 350 while I'm ordering one for my Whisper?

Maybe temperature and humidity are playing a part.  :-\

Doesn't the 350 have a reputation of eating scopes.

I have the same problem with many of my guns on very hot humid days.....I think it is weather related as well......BTW what does your 350 shoot fps wise?
