what's your take on them?
I'll bite.If one case has .012" thick neck wall and another has .016" thick neck wall, if both have inside diameters .001" smaller than the 30 caliber bullet's diameter, which one requires the most force to push it out of the case neck?
Both have .001 inch of "neck tension."
I referred to different cases, each with the same uniform outside diameter but different inside diameter.Are you are talking about the same case having two or even three different thicknesses..? Uneven wall thickness effects bore alignment from the way I understand it, so bullet tension is another part of the equation. Some say they do improve the accuracy some don't.
Items 1 and 3 are the same. Item 2 doesn't matter.I'll bite.
Depends on:
1. Bullet type/composition.
2. Chamber and throat dimensions.
3. bullet seating depth
