Highest airflow for a T1 bolt

[volcomboi]

Does anyone have any idea which aftermarket bolt for Dragun's the one has the highest airflow? Have there been any tests and if so can you tell me where to find this info? And which is better delrin or nylatron?

I use the APM Tigershark bolt on mine. It is high flowing, but i dont know where to find test results. And i think that delrin and nylatron are very similar, but i do know that nylatron is less prone to swelling.

APM is best. it has the flow of a lightning, and the weight and self-lube of a nylatron bolt. www.apmproducts.com

It would be great if somebody could post the flow of different bolts on a T1. It seems that the biggest limiting factor may be the hole on the body between the Valve an the bolt. It's the same size as the valve hole and about half the size of te stock bolt hole.
