jsr instead of trying to guess at the proper tightness. Why not use a feeler guage to measure between the detent cap and cartridge? It might take a while but if you change the amount the cap is screwed in by a small amount then test. You should be able to maintain a pretty good firing probability if...

Do you have a guesstimation of how much recoil the gun will have?
If you expect it to be quite high why not use the actual shocks from a car?

thats a beautiful knife

I have cooked quite a lot of cake inside my house. Somewhere around the ten pounds range. (Cake is awesome to have while paintballing ) It smells like candy cooking. (warning it will make you hungry) I have always used white sugar in my cake.

Cake mix plus C equals a slow cooking cake

Igniting the cake mid flight has a high chance of changing the trajectory of mini due to the amount of pressure that is relaesed by the smoke mix burning. I have used a very similar mix to propel objects.

you were right about it not giving an air tight seal it didn't really develop the leak until I tested it at 100psi. Going to try compressing the projectile that I cast into the cartridge to see if I might be able to seal up the leak. But that will have to wait till my next day off.

i was thinking this casting this type of ammo


I am going to try and stop by the hardware store tomorrow to pick up some fittings, to test whether or not the design will hold pressure. And if it does how much it will hold.

Read through all 37 pages of posts and wondered why I didn't see anyone suggest casting/pressing in the projectile. I was thinking something similar to an actual bullet. I will put up a drawing of what I am talking about tomorrow. questions only testing would answer At what psi will the projectile t...
