[QUOTE="Mikecr, post: 1255049, member: 1521"] There is no 'advantage' to it, nor to 'rat turds in a violin case'. Consider indicating the arc of a jump rope in action. You could place the gage nearest one pinned handle of the rope(line#2 pic) -> if you purposely want very low % of arc indicated. This is the lie behind neck benders. Now consider the rope frozen rigid in it's arc. Pin and spin the rope from it's center while indicating nearest one of it's free handles(line#6 pic). Here you read the full amplitude of it's arc. In this condition you'll know the rope is truly straight when it is(line#5 pic), and not until then. Ammo is straight when verified so on a v-block gage. With this, it chambers without case tension(chambered tensions), and excess clearances are no longer needed (as never desired) to relieve such a condition. It's a different approach I suppose. But I'm declaring that you CAN make straight ammo, and that's the best you can do. When you deny these things and chamber bananas your whole life, you create chambered tensions similar to resting a thumb on your action during firing. Move the pressure point from shot to shot and grouping opens. For the folks who apparently gave up on making straight ammo(because they heavily FL size), sloppy clearances seem to alleviate the problem. Their guns shoot better with this. And sloppy clearances leads to more sizing, which leads to more runout, which needs sloppy clearances. Classic loop... Opposite of this is understanding of, making of, and use of straight ammo. With this, clearances can be tight, leading to less sizing, leading to less runout, needing less clearance. A different loop, and there are actual 'advantages' in this. Different thread. [/QUOTE]
