Hectic, what's in your rifle?
My vsr had all PDI parts, laylax 6.03 430mm barrel, and firefly rubber. I was getting out to 260-280 at a mere 430fps with .3s. I never found a reason to go past 430fps, and it had incredibly repeatable accuracy. That and .3s start losing accuracy past 440fps, didn't wanna pay big money for .36s lol
Even at 380fps it was dead accurate out to around 210ft with .28s
Have you tried using .43s at 512fps?
