[QUOTE="J E Custom, post: 2028710, member: 2736"] Finally got back to testing the 30 Texan and I am Pleasantly surprised. It is based off the 375 RUM cases and the improvements boosted the case volume 17 grains. Forming the brass has been interesting and it appears (For now) that forming works best with out annealing first. The shoulders tend to collapse sometime while sizing down to 30 cal. if annealed even in steps, so the strength of the un annealed shoulder seems to prevent this. After resizing My intention is to anneal before loading to aid in final forming. The first test results were very good while fireforming using a 180 grain Ballistic tip and 103 grains of 50 BMG (I may back off to 101 grains for fire forming even though accuracy was very good while forming (.563 5 shot group, 3139 ft/sec lowest, 3158 ft/sec highest with a SD of 9). Accuracy is good enough that I plan to hunt with it and fire form at the same time. Once I get the cases fireformed, and load chamber size ammo, I will update with the final bullet size and performance. J E CUSTOM [/QUOTE]
