[QUOTE="Batsin, post: 2972430, member: 126867"] The 200 grain ELD-X was designed for the 300 Win mag and works in the 300 WSM and 300 RSAUM. The 300 WSM, RSAUM, and RCM were all designed to use the same bullets as the older Win Mag. If you want to use the longer-ogived 300 PRC bullets, you will need to seat longer than SAAMI spec to get close to the lands. With the short mags, you can gain significant powder capacity by loading long. As you can see in the photo of the loaded round, the ogive of the 200 gr ELD-X is short enough that some of the full-diameter shank extends beyond the case. The 212 grain ELD-X has a longer ogive, which is why I mentioned the long jump to the lands in a SAAMI-length WSM. The published G1 BC's are: .597 for the 200gr and .663 for the 212gr, so you can see that the jump in BC is significant for just a 6% weight increase. These are the best pictures I could find. [ATTACH type="full"]520458[/ATTACH] [ATTACH type="full"]520472[/ATTACH] The 200 gr ELD-X is in the middle, the 212 on the far right. FWIW, Federal also loads a 200 grain bullet for the WSM: [URL]https://www.federalpremium.com/rifle/terminal-ascent/11-P300WSMTA1.html[/URL] [/QUOTE]
