Most of the information I am finding on .30-06 trim length is max 2.494, with a trim to length of 2.484. Using the Lee lock stud/cutter system, my cases are constantly being trimmed to around 2.455. I'm using the length gauge correctly, but can't understand why it trims them so short. I have two questions:
1) Is it possible I have a defective length gauge rod?
2) Will trimming to 2.455 cause me any problems?
I've fired a couple hundred rounds so far with brass trimmed to 2.455 and didn't notice any difference in function or accuracy. I have about 3 loadings through a set of cases so far, and they are all still well under the 2.484 safety standard. Should I keep on trucking or should I look into a different trimming system? If it makes any difference, I'm currently ONLY loading rounds for the M1 and M1903A3 rifles. I don't expect match grade accuracy out of the rifles (nor do I have the skill IF they were capable of it), but I don't want my loading techniques to be to blame. I've only been handloading for a couple months now, and still have lots of questions. Thanks for any advice. This site is my number 1 online resource.
