[QUOTE="ARlife4me, post: 2728843, member: 105694"] Take example of 300wm whether being production rifles or custom builds (you or someone else built) of the same manufacturer, same barrel length, same twist rate..............well just call them duplicates/identical twins. Has anyone been able to use the exact same load in both with the exact same results (accuracy and speed with the same charge and bullet weight of the same manufacturer)? I'm thinking that trying to get the chambers being headspaced and throated the exact same is needed, but each gun having a mind of its own situation problem as guns do? Where too start? Fire both guns and take case measurements of both fired cases of both guns and compare. If the brass dimensions are different (most likely are) can you adjust headspace by_________________(fill in the blank(s)) to obtain needed measurement? Or do you need to adjust the chamber somehow (not sure what 1 could do and or how if possible). The previous sentence seams idiotic! Probably a good start would be by having/using the same reamer (whether you or another person does) with hopefully the same finish. I'm sure that I'm missing something in the process and any help would be appreciated! This is for learning before I try a would-be step. [/QUOTE]
