Freak boring VS detent VS both

[SignOfZeta]

I ordered 150 of the supposedly correct o-ring. When I’ve tested that they work I’m going to keep like 20 and mail the rest to Extreme Velocity.

I used the ASP mod and a tight bore one-piece and call it a day. I can count on one hand the number of rollouts I've gotten.

I both have the ASP mod and a Freak-bored barrel. If the paint is really small and I use a an oversized insert (because I forgot to switch it for a smaller one), I will get the occasional roll-out when I point the gun down. When I'm doing things properly (matching insert, pumping correctly, etc.) I have no issues whatsoever.
