[QUOTE="J E Custom, post: 1031056, member: 2736"] I am currently working on a line of cartridges that I am calling the TEXAN. They will use the same head space gauge and Hopefully the same (One set) bushing dies. and all will use the same brass, Everyone knows how much I like the RUM cases (A 404 Jeffries with the rim turned down to fit a mag bolt face) and this wild cat is based on getting what I think is the maximum out of this case. Body taper has been reduced to its usable limits of .010 thousandths over its entire length (Anything less and extraction could be an issue)and the body has been extended .092 longer. A 40o shoulder was used for case life and capacity. (Usable capacity with a 300 grain bullet and an COAL of 4.000 is 114 to 117 grains depending on the type of powder)for ease in feeding I used a center feed mag box. Preliminary testing shows that the 338 Texan will meet or exceed the 338/378 velocities with less powder and The TEXANs will fit a standard magnum bolt face. I just received the 30 Texan reamer and will start it within the next few weeks. I am considering other calibers for the series 7mm, .358, 375 and maybe the 416. I will post my findings and pictures after more test. The 338 TEXAN shot a .277 group while fire forming so I am optimistic that it will do better with formed brass and good loads. Wildcatting is fun especially when the goals are reached and performance exceeds expectations. J E CUSTOM [/QUOTE]
