There are several older threads around with a lot of load data and velocity info in them. I would definitely take the time to search them up and read through them. That said, i have a PVA 20” 6ARC AR that has about 110-115 rounds down the tube so it could still be speeding up a little bit. I have just started the berger 108gr elite hunters with Leverevolution. My starting load was 28.0gr with Starline brass and i was right at 2500 fps. I then jumped to 28.5gr and velocity went up to 2560ish. I will keep creeping up slowly to 29.0gr and watch for pressure.
This is just my specific setup and just know that every barrel will be different.
