Bullet ogive to base

[nddodd]

Hey guys, another question for yall. I was reading on another thread about how the difference in bullet ogive to base can be a problem in accuracy. Have any of yall noticed this and what is a reasonable difference. Do you seperate yours into different lots or is it not worth messing with.

I have about 300 bullets left out of a box of 500 im assuming these are all the same lot if so should the tolerances be good on these, they are 300gr smks if that makes a difference.

Just curious, always trying to find a way to squeek out a little more accuracy.


Thanks,
Nathan.

Try a search on "bullet bearing surface" or just "bearing surface". There are a couple good reads on the subject.

Yes---it is the actual bearing surface that determines pressure which impacts velocity as well as time in the tube. Measuring to the base of the bullet will tell you nothing as well as being inconsistent..
