[QUOTE="Joe King, post: 770155, member: 47325"] I think I'm reading the question a bit different. Your thinking that if the ojive is consistent that the cartridge OAL should stay the same as long as every bullet is seated the same distance from contacting the lands (assuming the bullets are of same manf and style i.e. 7mm 162 Amax )? While that would be ideal that isn't how it happens. The area of the Ojive that you want to worry about is the area where your comparator and your seating plug, and your rifling contact the bullet. Forward to the tip of the bullet from that point doesn't matter beyond the down range effect the minor change in BC will have. And it's dman near impossible for bullet manufactures to control the very forward end of the bullet Ojive and tip. You can however, if you trim the tip and point the bullet, but if your hunting with these bullets I would not do that as it can (and probably will) change everything about terminal performance As others have stated, you'll be better off worrying about the bearing surface length, one intersting thing I have noticed with quality bullets like Berger, or customs, and mass manf to a lesser degree. Is that if you sort them out to say about 0.002" in bearing length they'll be really really consistent in weight too. [/QUOTE]
