What's a good group? A group of ONE in a paper plate. Shooting nice groups of arrows in your back yard doesn't translate too well to hunting circumstances. i.e. your not likely to get more than 1 shot, occasionally 2 at the same animal. Best practice,IMO, is roving or taking 1 shot at that plate in your yard, and then put the bow up, whether you missed or hit-- that completes the session. Multiple sessions like this, at various ranges, angles, etc. through out the day, will train you to make good on the first shot-- this will give you the discipline to confidently, make good on the first arrow on game-- the ones after do Not matter. Have you ever noticed how easy it is to hit the mark w/ the second arrow, even if you miss the first-- its easy, you know what adjustment to make, and now that you have it dialed in, you can just pack the next 12 in there if you want-- but What's this got to do w/ taking animals? - You're not trying to shoot groups on them-- you're trying to get that first arrow in the chest. Because thes bows are so much fun to shoot its difficult to put it up after one shot-- its like taking just 1 bite of something you really like. If you vary the distance and angle on every single shot, and only allow your self to keep shooting if you had hit the mark, on the first arrow, it will give you incentive to focus, knowing that you don't have to put the bow up, until you miss the first shot of one of these varied range/angle shots. I think, a most will agree, that roving is the best way to learn to shoot -- Unfortunately, roving, is not practical for most of us, on a daily basis-- The one shot backyard practice is the likely the next best opt.--Unless of coutse you have your own 3D course.
