Was asked how to do this in a PM, so here you go. Applies to H3 and Reach. Goto your desired weapon tag, jump to "Barrels" (Protip, hit CTRL+F and type Barrels). Make sure to select the correct block index, some weapons have more than one such as the plasma pistol. Jump to "Crate Projectile" and then set it to a crate class object eg Bloc. Set a Projectile Speed. You can also null the initial projectile while you are at it. All done, go shoot some stuff I guess. I'll admit that a lot of basic info from the early days does not translate well into the modern plugins that we all use, if you want anything updated/explained let me know.
