In need of measurement on Hornady 140 ELDM factory ammo

[Estes640]

Can anyone tell me the Base To Ogive measurement for factory hornady 140 eldm? I’m nowhere near my reloading room/tools and I’m getting a barrel throated for it.

2.181 as measured with the Hornady bullet comparator.

I get 2.190.

A SAAMI spec reamer should suffice.

Thanks guys! Anyone have any hornady 143 eld x to compare? I measured my eld x Factory ammo at 2.1770”

For what it's worth; I got 2.1820" using the Hornady Bullet Comparator with the 5-26 insert.

Interesting results...not sure how specific you want to be but I also measured 10 of mine with the Hornady comparator (5-26) and got an average of 2.1742 (SD of 0.0016 / ES of 0.0055).

I guess that’s the comparator tolerance likely driving differences in the results...

Comparator tolerance differences. Bullet jacket thickness differences (variation from bullet to bullet). Seating depth differences (from Hornady), accuracy/resolution/calibration of calipers, how hard someone squeezes/pushes their caliper together to get a measurement....... lots of reasons for the differences in measurements.

Well said above. I’d say the comparators are probably one of the smaller tolerances of the bunch. I was just looking for ballpark. Thanks everyone!
