![]() ![]() ![]() Measure the bullet length, seat it to the Nosler OAL they used, subtract the brass length, the difference should provide a usable seated shank depth.ĭistance off the lands can produce a fairly significant pressure variance. I don't think there's a default that would work either. ![]() Unfortunately publishers don't provide this information, so there's no way of accurately using there estimates as a comparison figure for QL. SAAMI max CUP is like 52,000 CUP, and SAAMI max in Piezon is listed as simply 65,000 PSI, they do not correlate.Īnother factor that can have a fairly significant impact is seated shank depth. SAAMI CUP max indicates a much lower number when compared to PSI max. Cup and PSI do not correlate with one another. This right here could easily account for the variance you're seeing. OTOH, CUP is based on the copper crusher method. I think QL terms it as Piezo, which provides pressures in PSI. Which method does Nosler use for their pressure estimates, PSI or CUP. First off, and a mistake I've personally made is entering the wrong pressure measuring method. ![]()
