I went to the pro shop to pick up my bow today (had it reserved) and get a block 4x4, and decieded to play with some releases. I shot a couple of two shot groups at twenty yards with a truball rackmaster. First, the arrows were stacked. Second, they were less than an inch. Not really impressive to most people, but I usually shoot 3-4 inch groups at 20 yards. I hope my wife doesn't find the receipt where I spent an extra 60 bucks that she doesn't know about.
