[QUOTE="gregsjt, post: 1470331, member: 88091"] Thanks for making my point! That quote tells me that the body taper and shallow shoulder were designed to aid in extraction, the belt designed to aid head spacing. Isn't that what I said? "H&H cartridges traditionally featured a large degree of body taper and gently sloping shoulders in order to aid extraction of cases during worst case scenarios." The belt was added because the body taper and shallow shoulder made head spacing a problem. "H&H realized that a shallow shoulder would not give positive head spacing." Not being able to head space correctly then made extraction and accuracy a problem. "H&H realized that a shallow shoulder would not give positive head spacing, detrimental to both accuracy and extraction." Poor extraction is a symptom of poor head spacing. They fixed the head spacing issue with a belt, then once the case was able to head space correctly it would also extract correctly. Again, the belt didn't enhance extraction, it was designed to fix a head spacing issue. If it is possible to push a case to far into the chamber because a shallow shoulder doesn't provide enough angle for proper head space, of course it will then also be hard to extract. The belt stopped the case from being pushed to far into the chamber, that's it. Do belted cases extract more reliably than non-belted cases? [/QUOTE]
