[QUOTE="J E Custom, post: 2029315, member: 2736"] The 7 Texan will use the 7 RUM brass. I started out wanting to use the 375 RUM brass for all Texan's But as we all know, Not every idea works out like planed when you are in uncharted territory. The sizing process just works better using. 7 RUM and 300 RUM brass for those calibers even though they are more or less identical cartridges. Performance So far the 416 Texan has increased velocity Of a 400 grain bullet by 300+ ft/sec over the 416 Rem Mag with normal pressures. (I was after 2650 to 2700 ft/sec to fill the gap between the 416 rem mag and the 416 Weatherby without high pressures that normally are associated with high temperature's in Africa). The 358 Texan has bested all 358's by 1 to 200 ft/sec again at normal pressures. The 338 Texan has exceed my design requirements of 3,000 ft/sec with a 300 grain bullet and reached 3150 ft/sec with the big 300 grain bullet. At this time the 30 Texan test have not been completed but has easily top the RUM and is in 30/378 territory with less powder and pressure. The 30 Texan and the 7mm Texan are still a work in progress and when testing is finished I will up date. Just having fun J E CUSTOM [/QUOTE]
