[QUOTE="J E Custom, post: 995829, member: 2736"] Firearms were not designed to shoot anything but bullets. the quickest way to get into trouble is to stuff something else in the barrel/case. I fire form all cartridges using the correct powder and bullets. different cartridges need to be set up correctly to get the best results and a good fire form the first time. I build a lot of AIs and Wildcats and with the proper set up actually hunt with them while fire forming. I can expect sub 3/4 moa while fire forming and have come to expect 1/2 MOA most of the time. I am in the process of building a new wildcat design that I call the 338 Texan that starts with a 375 RUM case (average case capacity 104 grains of powder) and ends up holding an average of 118 grains of powder after blowing it out and lengthening it .100 and changing the shoulder to 40o, plus reducing the caliber of the case to 338. This case has everything possible done to it and while fire forming the cases with 106 grains of Re 33 and a 225 grain bullet the groups averaged .178 . So I have a good start on my load development while braking it in, and very well formed cases. Is other means of fire forming necessary ? NOT IN MY OPINION. J E CUSTOM [/QUOTE]
