[QUOTE="swampratt, post: 3771092, member: 15054"] I have a German 357 Magnum and I must trim my cases shorter than US specs. I also have a S&W 357 that accepts the longer cases and when I mix the 2 there is not any accuracy difference. I do not crimp my 357 cases and i do not run them through any Lee carbide crimp die either because I am shooting specifically sized lead cases and if I run the loaded cases through the carbide crimp die it will pinch my bullets down below my barrel diameter. Then accuracy suffers. When I did a brass fail test in .308 I did not trim my cases until they got so long that they were in the lands and the size difference was .035" Yes that is quite a bit longer. But accuracy at 100 yards with it was the same and again I did not perform any crimping. My 357 cases are 1.265" for the short ones and 1.290" for the longer ones. 1.155" I think is 38 special I did find mixing different cases changes accuracy. Case wall thickness and alloy of the case causes the big accuracy differences. Measure the ID and OD of those 2 cases after sizing it may surprise you. I have seen more than .005" difference. Even between the same brands but different lots of cases. Same thing goes for 45 and 40. The amount of sorting never ends. [/QUOTE]
