witch pilot valve is the best

[Ragnarok]

By nature, a QEV is an avalanche type valve. Expecting it to suddenly close before the chamber has mostly emptied is a pipe dream.

It's entirely possible. It's been done.

Take almost any of Brian the Brain's recent cannons. His Brass T-Bolt, Lupara, Bad to the bone... which all use hammer valve piloted QEVs for multiple shots from the same chamber.

Hotwired has also demonstrated a similar effect via a different method of partially venting the pilot volume. He can also get multiple shots from the same chamber.

I do generally have some idea of what I'm talking about.

but i think Brian the Brain's canon cant get the same power if he pilot the full chamber.into the barrel for one shoot
??

No, it doesn't get quite the same overall power - but he does get more shots out of one fill.

It all depends on what you're looking for in any given cannon.
