No problem, but how much does the pellet weigh?

yea that one sounds better, i know that on the larger one it has to move a heavier projectile but i still would have thought it would have been a bit better then just 77-84ms

well, unless I'm going to buy an emulator program...no HGDT for me :(

I wanted to model a 3/4"x12" hybrid with a 1/2" burstdisk run at 5x to see at what point lengthening the barrel would stop being worth the inconvenience

anyone used 8mm ball bearings and know what kind of speed you used then at and what kind of damage they can do for what speed

edit: decided 1m is to long if i am actually going to make it, so you think i could be a pain and ask if you could redo it with 60cm barrel and 40cm camber of same caliber as before and same ammo and so on... thanks

Wine is free. I think it's also important to know that a Mac OS is a UNIX-like OS, so Wine will work on Mac OSX (with a newer Intel processorand using the X11 server). Never tried running GGDT on Wine, though, so you might run into a few snags getting the dependencies to work.

Did you know that WINE stands for Wine Is Not an Emulator?

lol. I've heard that it works with HGDT.

What we should do is have a site that you upload data files to that will run GGDT or HGDT on them, then return a data file.

Sort of like the online video converters and that site that will tell you the shutter count of your DSLR.

Or D_Hall could compile it for Mac and Linux...

Just like PHP Hypertext Processor. Further proof that computer nerds should never be allowed to play with mirrors as children.

I've asked, he simply responded that he would if any one would be so kind as to buy him a mac :lol:

Thats a good idea, but I'd love to just sit and play around with the program without having someone else have to input my theoretical numbers and scenarios
