I have a pse stinger the draw weight is set at seventy two lbs and ive been shooting for about half a year getn better but im a little confused on how the grain system works for arrows and tips like to understand it a little better

Arrow tips are weighed in grains. The higher the grain the heavier the tip. Heavier tips often penetrate better, while lighter tips shoot flatter. This is a very brief description, but pretty well covers it. Once you decide on a certain weight "grain" tip you would like to shoot adjust your pins for different distances and if you change tip weights or arrow weights you will have to adjust your pins again.
