your elk hunt will not hinge on the difference between a 3" group or a 4" group and it will not be decided on whether your bow is going 320 fps or 340 fps and it will not matter if you've got 65 pounds of KE or 75 pounds of KE

if you do not have the legs and lungs, your elk hunt will most likely be unsuccessful. Spend a lot more time getting in shape and less time shooting your bow. Yes, that is true, as unpopular an opinion as it might be. You can shoot your bow once a week and be shooting groups fine enough to elk hunt with. You cannot excercise once a week and then go to Colorado and have expetations of a successful hunt.
