[QUOTE="swampbug, post: 3064307, member: 115992"] Neck clearance is whole other rabbit hole. There are many opinions and rationalization on this subjuect. This is just my observation. Again, 99.99% of shooters should never ever consider a tight neck chamber. Too many bad things can happen. Easy to ruin brass neck turning. Dirt, water getting into chamber causing over pressure or not being able to chamber a round. Etc. Cost. A tight neck chamber requires buying a barrel blank, having it custom chambered and muzzle threaded. Total cost $800 -$1,000. Purpose for doing it. If you have a hunting rifle and shooting out to 500 yards, are you really going to spend all the time and money to neck turn to extend brass life particularly when any accuracy gains are marginal at best. Accuracy - lets look at what the pros say. Bench rest guys neck turn. They belive it helps. When .001 in group size difference wins National championships, you would probably let me kick you in the balls if you thought it would improve your group size. F Open - arguably some of the best shooters in the world. There has actually been a recent trend away from tight necks/neck sizing in the belief that it just does not produce enough accuracy gain to offset the time and cost. Many of those that still do tight necks and neck turn, still neck turn to produce a .005 clearance. They are also fanatics about consistency and since they burn through several barrels a year, they use the same reamer to produce the same neck, and neck turn all brass to the same thickness so that one barrel to the next and each brass lot they use always has the same neck chamber size, brass neck thickness, so therefore they always have the same neck clearance. PRS - the best run and gun shooters. Most don't neck turn. Not enough accuracy, not worth time and effort and cost. Can lead to potential problems chambering rounds. [/QUOTE]
