[QUOTE="rscott5028, post: 492952, member: 24624"] I'll defer to the experts on internal ballistics. But, even the experts tend to dumb it down for the rest of us... [url=http://www.hornady.com/ballistics-resource/internal]Internal Ballistics - Hornady Manufacturing, Inc[/url] I'm not even sure that there's a single right answer for your question/theory since it may depend on seating depth, headspace, case head diameter, extractor/boltface, runout, and many other factors. Regardless, I think most of us understand that there are many variables. Some can be estimated, anticipated, and/or measured. But, they all add and/or subtract from eachother thus making every rifle somewhat unique and requiring load development for nitty gritty fine tuning. I've seen many resources that indicate that .003" TIR or less is not going to adversely affect accuracy/repeatability. So, I work towards .002" or less while concentrating on other variables such as headspace and neck tension, etc... It's probably easier to avoid all of the things that will undoutedly decrease accuracy. ...like making crooked brass -- richard [/QUOTE]
