thanks jrrdw

do any of you know about a 2in check valve that is rated to 4500 psi

ball berings make great projectiles if you want to cause some destruction

agreed defiantly do not charge it over 100 psi until you know exact psi ratings

1 depends on duster valve and wether you use 3 or 2 and 1/2 but make sure it is good pipe but I can not determine exact psi because you did not give me the exact parts 2 it is good to have long barrel for max velocity so 8 foot barrel is not crazy and make sure you have right adapters to get it rang...

once I get my own PC I will since I am running on school chromebook

thank you all thought for being great members of a great forum

burst disks do give better velocity than valve usally

i will a soon as i get a pc that can put photos on here since i am running on a old school chromebook

okay I will as soon as I get a alt account that's not on my school Chromebook trust me it is pretty hard to post images on a school chromebook so I will as soon as I get a computer of my own which might if I am lucky happen in 1 week to 2 weeks

I was saying my gun did and sorry I should have clarified

it did not use a sabot and had to use the deflagation dang it that word is very hard to spell anyway back to the topic it did not use a sabot just a solid steel projectile besides I have used liquid guns a lot more and they seam to be more reliable though if you really wanted some velocity I whould ...

not true as I am a friend with a gunsmith about that powder gun you just have to have a massive case with much higher powder concentration and faster than 8900 is possible with enough fuel and air for spudgun if you use the right feul

liquid fertilizer mixed with starter fluid and gas
in 75 to 20/15 mix works well

okay typically it would have to be larger than 2in but smaller than 3 in so 2 and 1/2in pipe works
