[QUOTE="Innovative, post: 138944, member: 527"] I agree with Chawlston when he said that neck sized handloads need to have the shoulder bumped back, AND the less you resize a case - the less it will stretch, AND the less they stretch the longer your brass will last. However, I have also seen neck sized cases (bumped back) that would not chamber due to vertical compression causing the pressure ring to expand. This happens because the pressure ring is thinner brass, and even the slightest downward pressure from dies can bulge this area very slightly. On neck sized cases it only takes an extra thousandth of an inch. Another example of vertical compression is when you neck size thin necked calibers (like the 30-30), even the case neck can buckle enough to make handloads jam - just by adding a slight crimp. Anyway ... when you FL resize a case and you can feel your press working hard. This resistance comes as the pressure ring is being compressed on a tapered case. All I'm suggesting is to keep an eye on the pressure ring. It's "something else" to look at. Make sure your handloads will chamber, especially when hunting dangerous game. Keep in mind that neck sized cases are far more likely to jam with just a single grain of sand in your chamber. Not every shooter is shooting from the bench under ideal conditions. - Innovative [/QUOTE]
