[QUOTE="barefooter56, post: 1139188, member: 85389"] whitesheep, I have found that in some cases they do or its really close. If I had a CBTO off the lands of .010 for a Sierra .30 cal 155 grain bullet and wanted to try a Berger .30 cal 155 grain bullet. I would make a dummy round for the Berger 155 to the lands to find whats its CBTO has to be for it to be .010 off the lands and test there before starting on the lands and working back. Also If you use the Sinclair overall length tool. You use one of your once fired cases with it so you don't have to have a modified case like the Hornady/Stoneypoint tool requires. [/QUOTE]
