Range indeed. .36s in theory should have better range then .3s IF the hopup can give it the right backspin. Unfortunately stock TM hicapas from what Ive seen dont even have the hopup to properly spin .3s unless you bend the internal arm a bit or replace the rubber. On max hopup my stock 4.3 shoots great with .25s. It has seen a lot of rounds though. .3s are much more accurate but they drop earlier due to lack of hopup.
