Different bullet lengths
« on: October 11, 2008, 03:50:27 PM »
Hello All, its been a while since I posted on here. I have a question. I thought I was having problems with my press/dies because I was having trouble getting my OAL to come out the same every time so I finally thought about measuring the individual bullets and the length of some of them varies quite a bit. I don't remember the exact amount but some were +\- .01 or even a little more. What do you'all do in this case? I guess you just find a middle of the road one set up your bullet seating die with it and just trust that the small amount the variance might be wouldn't make that much difference. Otherwise I would have to re-adjust my bullet seating die before each bullet and slowly screw in the die until it exactly reached the OAL I wanted. Thanks, Charlie

Your seating die contacts the bullet at the ogiive.  It seats from that point, without regard to the OAL.  Each style of bullet will have a diffenent contact point for seating, even thought the bullets may be the same weight.

Is this clear or have I confused you?

For bullets like the Hornady V-Max:

I will measure OAL like you are doing.
But with lead tipped bullets like the Hornady Spire Point:

I utilize the Hornady Lock-N-Load Bullet (formerly Stoney Point) Comparator (using the ogive as "charles p" mentioned) for a more precise measurement, as the soft lead points tend to be flattened and lengths can vary greatly.
