RE: Accuracy problems
Manually cocking can definately cause the string to be uneven and will cause the bow to shoot right or left. If it is 5-6 inches off left or right that is the most likely cause. A cocking rope is a really a must not only will it ensure that the bow is cocked evenly it will also cut the pull when cocking by 50% making your trips to the range more enjoyable.
I always number my arrows with a permanent marker on the fletching to see if there are any "fliers" that do not want to group with the rest.
