Got a vis engine breaking some paint on the bolt. Pressures are 170/70 ish. Cron was 280fps. It’s definitely breaking on the bolt it was covered in paint. Any ideas what it could be?
Also, what is your BDD setting? Is your VIS tending to break paint wen your loader is almost empty? What kind of loader are you using, and have you tried using a slightly larger barrel back/insert than the paint you are using?
