[QUOTE="BountyHunter, post: 831588, member: 12"] Sizing does work harden brass. When fired the brass expands and the chamber expands, the brass shrinks down and is easily extracted. However, over time that expansion/contraction will work harden the brass and it will not shrink down in the chamber enough to release at some pointand you get the inevitable brass stuck/tight and the bolt click. That is IF you are reloading anywhere near max. As you have stated you do not do that and you stay with smaller cases, so I can see your unfamiliarity with this concept, no matter how well documented it is everywhere. As for your question what is the gain with higher pressures? Easy, more MV and flatter trajectory with bigger bullets! Not a difficult concept to grasp IF you LR hunt and for larger animals. As for Quick Load, well [B][COLOR=#bc2222]WARNING: QuickLOAD is a computer simulation of centerfire cartridge performance.
