[QUOTE="KYpatriot, post: 1007824, member: 48028"] Well it depends on the confidence level you want. If you want to KNOW what the real SD is you have to shoot a lot...and like you said that adds up quickly. The point of my post is that with five shot sample sizes you can't really say with much confidence that the unfired brass is really shooting tighter spreads than the fired brass...it is very possible that it just happened that way for those two strings. So don't put too much effort into changing things just because of two five shot strings. What I would do is to pick a load, shoot a string to get your velocity for the ballistic calculator, and run the load and see how it shoots. Instead of wasting rounds at 100 yards with a chrony shoot it at distance and get a feel for how much vertical you are getting. Collect this data the same way you would SD and ES and use it the same way. If you don't like the amount of vertical you are getting in your long range groups then go back and change something. You will have learned that your velocity isn't as consistent as you like and along the way you will have enjoyed the shooting a lot more and probably improved your wind calls. Bottom line, shoot it at range for awhile and see if you really do consistently get the kind of vertical spread the SD would have you believe. To really know for sure, you need much larger sample sizes and you might as well get the data through real world long range shooting rather than data collection at the bench, unless that is just your thing. If you collect data and record all your shots, load development never really ends lol. [/QUOTE]
