I got an Ozark Mountain Longshot a few weeks ago in black and green. Stewart (cannonball55) set it up for me to also be able to use flatbands. It is constructed very well and the paint job looks great. My first 50 shots were with 1/2 marbles and they worked fairly well with the tubes on the slingshot. 1/2 inch rocks work pretty well also. Both of those seem light for the tubes. Since then I got some 3/4 to 1 inch river stones and they worked very well. .50 lead, .62 lead and some of my collection of old computer mouse balls flew really nice. I placed an adjustaband from Perry at A+ on the slingshot and that worked well with the more uniform ammo I tried. This slingshot has power and with the wide forks it will shoot a wide range of ammo. My only problem is a very worn out forearm. You won't run out of ammo out and about with this slingshoot. It can't be pocketed, but maybe in a backpack to take on a hike in the sticks.
