I have owned my 50 cal.tc encore for several years and have loved it and harvested alot of deer with it. Over the last couple of years ive been having trouble getting it to shoot decent groups. When it was newer I was quite immpressed with the 1.5 inch 100 yrd groups I was getting. Now however the groups seem to be closer to 5 or 6 inces. At first I tried replaceing my powder and primers ( 777 pellets and winchester 209 ml primers) because i thought maybe they were getting old. That didnt seem to help so I was hoping for some ideas?
Im sure its not the barrel because when it is clean it is bright and shiny with no pits ( a little rough where the powder ignites). could it be the hindge pin? It has a little play when the barrel is open but next to nothing when it is shut. I am considering selling it and buying a omega instead.
Any help would be greatly appreciated thanks!
