if you dont use such a high fork and have lower fork tips you can shoot arrows with your slingshot as it is without any silly modifications to the slingshot itself. Your pouch can hold the arrow in place no need to have a string for the knock or any of that technical hooha..
Steel ammo and arrows are very different.
Steel ball weighs about 30 grains, hunting arrow weighs 400-500 grains. You need more energy for arrow shooting. Very heavy arrow (comparing to steel ball) = very heavy rubber, so draw energy is used for the movement of heavy rubber too, not just the arrow.
Draw lenght for ball shooting can be very long (butterfly, albatros style), draw lenght for arrow shooting is limited by the length of the arrows. Shorter draw lenght (power stroke) = slow motion.
Conclusion: using the same slingshot you can shoot steel ammo very fast, but arrow will be fly very, very, very slow. Sorry, "silly modifications" are necessary!
