Fired my 250z an uncounted number of shots this morning but I am sure it was around 100-shots or so.
I told on here yesterday that my 250z was throwing an occasional flyer while using AEA 21.9gr. Solo1 offered me a good bit of advice on checking the bore for high/rough spots that might be grabbing the pellet. I did not do that as I had polished the bore meticulously when the rifle was brand new. The bore scope showed a near perfect looking bore. Otherwise I would have followed that advice.
Yesterday I decided to try increasing the regulator/velocity very slightly to see if the flyer issue showed any change, and it did. After increasing the regulator about 50psi the flyers appeared to come more frequently, and slightly worse POI. I have had a feeling for some time that my original tune was pushing the velocity right up on the edge of where the AEA 21.9gr wanted to fly. But, I wanted to push them a little higher just to see what happened.
So, this morning I decide to go the opposite direction on the regulator. My original tune had a reg. pressure setting of 2050psi. Yesterday I pushed it up to 2100psi. This morning the gauge needle is dead-nutz on 2000psi.
I'll need to shoot the rifle a few more days to confirm results, but I can honestly say that my flyer issue appeared to be gone during this morning's shooting! I was able to put down several 5-shot small ragged hole groups back-to-back without a single shot ruining the groups.
Of course, there are so many other factors that play into the results of any particular morning of shooting that I am not claiming I was able to tune-out the flyer issue just yet. If the flyer issue appears to have gone away, or minimized after a few more shooting sessions I'll report it as fact. But, I am feeling confident that I am on the right track toward resolving the flyer issue.
