[QUOTE="VinceMule, post: 2789962, member: 122164"] I have been in two ballistics labs. They have different barrels/guns to pressure test with. Each gun/barrel has a different bore dia, and different throat lengths, with their lot number of powder, primers, and bullets. Bullets shot may have different pressure rings and this can vary over time as bullet-making dies wear, the bullets get larger in dia. [COLOR=rgb(184, 49, 47)]So, the info in loading manuals is meant to be a guide as to max loads in THEIR barrels and components.[/COLOR] A reloader has to know this simple TRUTH! Brass starts showing signs of serious failure around 70,000 CUP, I don't need pressure testing equipment. Also, educate yourself on which actions and designs are the strongest. [/QUOTE]
