Sierra 69g HPBT variances

[Grommit327]

Reloading some bullets that I have had for a year or two and I am getting 10 thou variance in the COAL. Everything is consistent at the ogive but I have never seen so much difference from the ogive to the tip. I also noticed there is quite a bit of weight difference...about 1/2 grain in the handful that I weighed.

Anybody experienced this? I would expect as much from a lower quality bullet but not from match bullets

The tips will vary on SMKs. This is normal. I have been loading 69s, 77s , 80s and 52s SMKs for many years. The SMK is one of the most accurate
bullet you can load. I use the bullet comparator to accurately measure the bullet seating ogive.
