[QUOTE="AZShooter, post: 947233, member: 5219"] A friend of mine who is a 1000 BR shooter with several records to his name asked me to turn the belts off of 50 cases. He had a 300 win mag match chamber made without the belt! I used a collet chuck and discovered that machining off every belt was a real PITA. I also noticed that some belts were not that concentric and a tiny bit was often left on one area with the rest being flush. Some minor sanding/polishing fixed them. He later got a different reamer and included the belt. He admitted he gained nothing in removing the belt. The only advantage in removing the belt might the brass stacking better in the magazine. There is an advantage to having a belt. The belt helps to hold the cartridge in place for the first fireforming shot. No false neck or bullet engagement of the rifling is necessary even if the shoulder is far forward of the virgin case. [/QUOTE]
