Randy1911, don't be confused. If all you are doing is hunting, 1 and 1/2 inch groups with a 30-06 is fine. If you are shooting for groups, you need to start with the right state of mind in putting your rounds together, and a trickler is just ONE step in the process that requires you to weigh each bullet, each case, size your primer flash hole, use the same brand and lot of brass so the volume in each case is exactly the same. And the finished product is EXACTLY the same as the next one on each round you put together. We are not talking about windows but peep holes and then you can get groups that are 1/2 inch or less.
But let me warn you, the first time you shoot a group of three rounds that measures 0.25 inches or less you will be hooked on accuracy loads and spend a lot more time and effort in putting your loads together and making sure they are just right.
