The gun should be as accurate as possible... I currently have a Remington 700 bdl in .270 that shoots 3 shot groups about the size of a quarter, but I want to draw that shot grouping tighter... I would love to shoot dime sized groupings! These are from a bench. I dont have the confidence in myself to make a long range off hand shot... I shoot with a rest always as I seem to have steadiness of a building involved in an earthquake! so that is why i always use a rest as well as my sling... to bring steadiness! If i was to shoot at long range i would prefer to put together groups of 4 inches or less... that way i know that even if i miss a little in one direction or another I will still kill the animal with a single shot! That is the most important thing!
