If the detent works correctly and you have a tight magazine, you won't need a paddle because the air pressure will push the paintballs in the mag up. You'll also be wanting a spring at the top of the mag, to stop the paintballs crushing eachother.

here's a blow forward barrel design that i think would be easier to build, but i hope the barrel will not be too heavy for the loading action to work effectively. It will probably have a sliding barrel support to reduce the stress on the blow forward action

Mark.f used that concept on his full auto marble launcher, so yeah it will work.

I just want to warn you.. there should be no need for the paddle... just put a second detent behind the mag where you paddle is now...

And, if you ever use solid... hard projectiles... prepare to replace that front detent every few 100 shots.

I'll build two loading prototypes, one of each.wish me luck

luck wished 8)

Use an o-ring detent and it won't wear out for a long time.

sorry to kick this up, but I'm thinking of using the blow forward barrel for this long put off project. I can now use pressures up to 700psi, so I think it may be a viable options, but do you think the barrel will be too massive even with sliding supports?
