I stopped grouping arrows a long time a go...If I go out and take a shot on my 3-D's and get a heart/lung shot on 1st arrow I leave it at that and when I practice useing the Morrell super duper 16 spot bag thats what I do...One arrow at each spot at differant yardages,same with the Block target...
I do however sight in new sightsat 20-30-40-50 and now 60yrds but Iam re thinking that as to going 15-25-35-45-55yrds then I will try and get good groups then after that its back to one shot one spot at unknow yrds...After all its that 1st arrow that counts in hunting.....But if I shot IBO or something then I would be a tight group getter.....
