[QUOTE="Swamplord, post: 1103481, member: 2460"] Regarding the 500 Jeffery ....... The difficulties with extraction were associated with older 500 Jeffery brass that was much thinner in the web area and the cartridge is nearly straight walled, upon firing heavy bullets with hot loads in hot temps .....cases expanded to fill chamber and got "stuck" by over expansion/stress, the rim was basically stripped off by extractor failing to remove spent case, Using modern brass from Bertram, Norma, Jamison AND applying case taper of at least .015" eliminated any extraction failures with even the hottest loads that bust Jamison brass primer pockets with two firings [/QUOTE]
