[QUOTE="Shawn Carlock, post: 114843, member: 4"] I sort mine first by measuring from base to ogive, then take the biggest lot of the same and measure the bearing surface, I take the biggest lot of the same and trim them. These are the best of the best. I use these for anything important. I finally took some of the worst of the worst and shot some groups against the best of the best. Here is what I got. W of W ES - 16 fps 100 yds average 5, 3 shot groups .364" 300 yds average 5, 3 shot groups 1.089" 811 yds average 5, 3 shot groups 4.194" B of B ES - 6 fps ( this later turned out to be really important ) 100 average 5, 3 shot groups .328" 300 average 5, 3 shot groups .891" 811 average 5, 3 shot groups 3.247" I have not shot both at my 1276 yard plate but I believe that the vertical spreads I am getting are directly accountable to the small ES that is the product of the sorting process. You won't see a big difference until the ranges get long. I also shot some sorted but not trimmed bullets against sorted and trimmed bullets @ 811 yds. The group difference was none exsistant so from an accuracy stand point the sorting was worth it but trimming was not. I trim the best of the best because I use them for LRH and the open up more and more consistantly when you trim and clean the hollow point out. The trimmed bullets did drop .50 moa lower @ 811 yds. Now to the real question, is it worth it, that depends on your performance expectations. If you want to pull groups from 1200-1300 yds that are in the 5-6 " range I believe that you have to do everything you can to get there. If you simply want to lung a deer out to 800 yards sorting and trimming is a waste of time. Again this is what I found, if anyone has other data I love to see what they ended up with. [/QUOTE]
