Working with 7-08 brass. Max length is listed as 2.035. I've been told a trim length should be 2.025. Is it OK to keep loading fired brass as long as it is still under the 2.035? I was assuming the 2.025 trim length was specified so brass wouldn't have to be trimmed every time it was fired but didn't know if there was still a safety margin based on instrument accuracy built into the 2.035 measurement. For example,since I'm using a cheap Harbor Freight caliper, should I trim at 2.033 or 2.034?
