[QUOTE="eshorebwhntr, post: 978128, member: 17112"] Check the bedding for inconsistency. Check that the action screws are torqued, not just tightened randomly. Try to verify the concentricity of your brass necks. If its a wild flier and the gun is an otherwise shooter then the flier could be chambering funny and the bullet could be leaving the case more out of true centerline than the other 4 that grouped seemingly well. Make sure the chamber and neck/throat area is very clean in addition to your barrel each time you scrub it out. I know you said your chronograph is giving you good numbers but maybe try shooting a 4-5 shot group at 400-450 to back it up (ie. prove there is minimal vertical stringing stemming from high SDs/ESs). Do it on paper as opposed to steel if possible so you can again check for bullet stabilization. I like a pallet covered with butcher paper and an orange circle in the middle. This also will give you a warm-fuzzy on how accurate your drop chart is (if you're using one). Good luck. I hope you get something that you're happy with for your hunt. [/QUOTE]
