[QUOTE="Hugnot, post: 2020023, member: 115658"] I would use a 180 grain or less and use the Miller stability estimator to check out adequate stability for the altitude & temperature you intend to shoot. The JBM stability calculator provides estimated Sg values using bullet weight & length. [URL unfurl="true"]http://www.jbmballistics.com/cgi-bin/jbmstab-5.1.cgi[/URL] These calculations enable the plastic tippy thing, of negligible weight but of length consequence to be considered in a Sg calculation or estimate. The JBM Sg calculations use the Miller method, which I have seen duplicate the results of that found on the Berger site, except the Berger Sg estimates don't provide for plastic tips. Most plastic tips are between .14 to .15 long. I have found the Miller Sg estimator method to be conservative - I use it before buying bullets. 11 twist is not usual for the .300WM. Shooting elks is usually not done on warm blue bird days. [/QUOTE]
