[QUOTE="cdherman, post: 1384181, member: 12282"] You should however, combine the Hornady case comparator set with the base to ogive (BTO) comparator. With the pair, you can bet a better idea where your bullets are exactly from the lands. Unless you have the BTO comparator dummy cartridge made from a 2-3x fired round from YOUR gun(one that was only neck sized) then the Hornady comparator cartridge will measure the length of your rifles headspace SHORT. This will mean that you will UNDERESTIMATE how long the BTO of you loaded cartridges needs to be, using your own neck sized or shoulder bumped cases. This is probably most critical, IMO, if you are trying to get close to the lands. Its in the .001 to .0010 range where very minor variations seem to really mess with things. I think a lot of very experienced shooters will either jamb into the lands .005 or .010, or stay off the lands by at least .010 as well. If you are trying to get closer and maintain consistent jumps, you need to really be on top of a bunch of variables, the BTO being only one. Anyhow, thought I would mention this. Its been discussed before in other threads as well. Great product. Know its limitations.... [/QUOTE]
