I don’t think I’d be drawing much conclusions from just the one test pic.
@.130 you have 4 shots practically in one hole. If these were the first two shots of each 3 shot group at that seating depth, I’d say it looks pretty good with a superlite.
But from my own experience, if those were my groups, I’d probably be working with the gun more before I made any decisions on it one way or the other.
Have you shot other ammo in that gun?
Have you shot better more consistent groups with a different load?
What kind of rest setup and cool down period between shots?
I think there will be more questions than answers from people.
I made a thread about horizontal stringing that helps discuss my learning curve with a lightweight rifle that may be worth the read. I learned a ton through that process.
Edit: PS
I also only change my seating depth by 0.020” each step when I’m looking for optimal coal, so using double that amount you may be missing some key info - like an optimal seating depth between your steps
(The bottom three shots on the top right target are from using the magnetospeed on the barrel while aiming at the target below, so just pay attention to the 0.250” group)
