So does the length of .243 rifle brass affect the POI? The reason I ask is I normally trim my brass to 2.038. I give it .001 variance in either direction, but try to get it right on 2.038. I usually have to trim it even if it's once fired brass. Anyway, I bought some Winchester never fired brass from Bass Pro a few days ago and decided to measure it today. I found the results shocking to say the least. It varies from 2.031 to 2.039 depending on which case I measure. Most seem to be in the 2.033 through 2.035. Some are over and some under though. I'd never let it vary this much if I was trimming them, but that's not fully what worries me. My book also says to trim them to 2.035 so some of them are shorter than that. If I load these up can I expect them to shoot to the same POI as the ones I trimmed to 2.038? I don't want to have to adjust my scope for these loads. Is it fine to go ahead and load them up? The next question is will I be able to expect these to be accurate and each of them shoot to the same POI? I don't want to have huge groups because of the brass being different lengths. So from you guys that have dealt with this am I fine in both cases? Or am I going to experience a headache here?
