Like I said-because I like to over complicate things I did some goggling and YouTubing and evidently there is a LED light option for indoor use with the Caldwell Chrono’s. I Billy Bobed one up with some duct tape and some LED lights I had laying around and repeated my test inside my garage. On average it increased the speeds of both rifles about 20 fps with each pellet.

Meisterkuglen 8.4gr
H 611 L 602 Average 606 fps
RWS -R10 8.4gr
H 611 L 605 Average 609 fps
I don’t know what’s considered spec for either rifle I’ve read the D75 tends to be a bit faster than the FWB 601. Again I wasn’t looking for a speed contest both rifles were consistent regardless of the pellet fired.
I think Iam done playing around with the Chrono and my wife says I spend to much time in the garage 🤦🏻
I do have a set of seals for the 601 but Iam not sure it’s worth messing with right now.
