Sierra .243 110 SMK measurements

[Deleted member 10043]

Does anybody have the following....???

BT length
Small BT diameter.

I'm creating a line for it in the .bul file in QL. My version doesn't have it. Thanks in advance.

The length of the bullet is 1.345. The length of the boat tail is .171 and the diameter of the BT end is .200 as best as i could measure it. It is a pretty rounded corner.

BTW, I came up with something similar and averaged the sets of measurements. I measured it with caliper and took a careful photo of it on columnar pad and measured using OnTarget. Close enough for QL. If anybody has the Litz third ed. it would be interesting to see what he published.

Tee hee, we were nearly spot on (+/- .1mm). I got the latest update. I'll leave that line above alone. It can be added to the seirra.bul file manually for those that don't have the current QL data. You'll have to figure out how to do it if you are so inclined.

BOAL = 1.345
BT length = .197
Small BT Diameter = .193
Nose length = .730
Bearing Surface = .418
