[QUOTE="MNbogboy, post: 2032405, member: 18849"] [ATTACH=full]228271[/ATTACH] Here is another take on the above. Block 1 sets bolt face to muzzle without block 2 on the rod. Block 2 is then reinstalled and rod is brought up to bullet tip where it gently is pushed up to the lands with a second dowel (wood/plastic). The block is machined exactly to 1.000". The measurement between the blocks + 1.000 is the COAL. Subtract the comparator measurement of bullet ogive to base from bullet length to arrive at your CBTO. After developing your system of doing this it is fairly fast & repeatable. Frankfort Arsenal makes a similar "plastic" version but it is too flimsy in my humble opinion.[ATTACH=full]228271[/ATTACH] [/QUOTE]
