Hi,
What can cause a regulator to go from 140 to 170 bar...?
Spring is around the corner so I decided to "re-zero" my Bobcat Mk2. I took it out back and started shooting at 25 meters. As always, the gun puts pellet after pellet in the same hole. This was done on high power. I then decided to zero the scope at low power as well. I have a MTC Viper so having multiple zeros is not an issue.
Here is the "weird" part: Upon switching to lower power, my pellets did not just drop, but they also went to the right?! The first shot, after switching to the lower power setting, always went farther right than the following ones?! I would say about an inch at 25 meters, whereas following shots would be off by maybe half an inch. I would like to also point out that once I was shooting at lower power for a few shots, the groups, although to the right, were pretty tight. Not as tight as on full power though. Once I switched to high power again, the pellets would be "centered" again.
This whole thing really "threw" me off, as the gun never did this before. Sure, lower power would always make the pellet drop, but NEVER make it go off center?!
After shooting for a little bit, the "first pellet way off center" issue was suddenly gone??? The pellets would still be off center a little bit, but the groups got way tighter, and no more flyer at the beginning.
So, that is when I realized that my regulator pressure is set at 170 and not at 140, as it always has been?! I have no clue why my regulator suddenly went up.
That said.
1. What can cause a regulator to just change?
2. Since when does lowering power make pellets go off center? Especially when my gun has never done this before.
3. Why does the issue seem to be gone once the tank and regulator have equal pressure?
Thanks,
Kmd
