Yes

Here's a pic but you need to zoom in a bit to see the score lines.

What does this mean?

Looks like your pellets are clipping end cap on way out, try shooting without end cap see if it groups ie pellets all hit in same place, if they don't take the shroud off, it might need a little bit of heat around breech area but should unscrew, I have just had same problem with one of my s510s, I just drilled the exit hole in the moderator and it's now fine. Let me know how you get on Rog

Just another thought, if the scoring in the end cap isn't that deep and you have access to a pillerdrill it looks like you would have enough meat left to bore it out with a 9mm drill, it could be a cheap option, and it is one that I would go for, I doubt it would be any louder either. Rog

I have tried filming the shots in slow motion but my camera is not the best for that. I have tried 120fps, 240fps and 480fps but I still can't see the pellet flight like you do on all those youtube videos.

Where is best to place the camera too see the flight? I was hoping to see whether or not there was any pellet wobble.

If your s510 is fac .22 it's probably doing 800 plus fps if 12ftlb about 580 fps. Rog

It is a FAC .22. I have chrono'd it at 283.59m/s avg over first 10 shots, 291.27 avg over next 10 and 283.68m/s over the last 10. That is around 938f/s.

Based on those figures the pellet would still be going at 741f/s at 50 metres. So are you saying it is all too fast for a camera?

Am afraid to say I really don't know about such things, my main worry would be getting it to shoot where it's meant to, the power output isn't a problem. Rog
