Smirkingjacksrevenge, if I use a firing cylinder of 10 cubic inch with near future plans of shock pump pressure and use 12mm slingshot ammo will the 10 inch cylinder be overkill? Really wish I could get the program to work rather than keep questioning you

I will.tryy GGTD on another computer tomorrow and hope all is well, otherwise I don't know what's up and I wonder if someone would be willing to Zip up their working program and email it to me?? I know its a big ask but I really want to try out various factors for myself to try and obtain a decent predicted performance frommy gun specs.
Just another quicky with a 12mm/~just under 0.5" with about 250psi on hand using steel BBs how much difference would a 60" long barrel compared to say a 72" barrel compare would it alter performance much all other factors being optimal?
thanks Ian
Ps just ordered a ahock pump for temporary use!! Sounds like hard work!
