[QUOTE="243winxb, post: 1632763, member: 97793"] Slow burn rate powder and light bullets may not fully expand the necks on firing. Example- 243 win , 68 gr Berger bullet, IMR 4350 powder. Near maximum loads are needed to fully expand the necks. The hardness of the brass is another reason expansion may be different. . Annealed brass will expand easier. Look up the chamber specifications of both. [URL]https://saami.org[/URL] [/QUOTE]
