It is from advancedspuds.com
I built this as my first launcher and it works amazing! i can't find the spuds after launch but i never went to a field
I think that it is probably better than a normal chamber because it would concentrate the force through the reducers. What do you think

Most reducers like that are dwv and not pressure rated. It should be ok for a basic combustion though.

I think the performance doesnt change a crap when the chamber gradually reduces like that (with a poabably UN-pressurerated fitting).
Think this way:
If you take out the sloped section and replace it with a straight one (a bushing reducer) your chamber is somewhat closer to the barrel.
But still, it doesnt matter.
