[QUOTE="AZShooter, post: 968366, member: 5219"] Recently Gunwerks modified their reamer with a larger neck diameter. The reason is that some of the Hornady brass has shown up with thicker walls. There were some reports last year of high pressure with sticky bolts and flattened primers when some handloaders tried the original Gunwerks suggested load with H1000. I would suggest you find out what your chamber's neck dimension is then determine if there is sufficient bullet release clearance before you begin loading. A friend had SOME of the brass that was IIRC running .017" thick and his chamber had the tighter neck dimension! We had to turn all his brass for proper bullet release clearance. A simple test if you have fired some rounds is to see if a bullet will slip into the fired case mouth without resistance. If it is tight you risk an over pressure situation with that random piece of brass that is just a bit thicker than the rest. If nothing else it will cause irregular velocities and flyers. [/QUOTE]
