Hi @Daanios, nice choice of RIF!
1.3J @ 0.3g BB = 385 FPS @ 0.2g! Luckily working backwards with joule creep will reduce that.
I think you need to decide how you want to use your MWS, but you get a lot of joule creep, so tune to your Holland limit of 1.3J on 0.3g BB, that should net you a lower joule reading on 0.2s, making it safe over here
As per usual, don't get hung up on FPS with an MWS, they have exceptional range regardless, most of the time more FPS only gives faster time to target.
