Diameter Measurements of an Assortment of .357 Ammo [Analysis]

[Bernie7]

So last night I decided while I had some very fancy calipers on loan from a friend I’d check all the .357 ammo I had.

For reference, I selected 3 random pieces from each pack and measured them twice. Once while at a 0 degree angle and then again at 90 degrees to get the most accurate assessment. I performed checks on the Lehigh rounds to make sure my instrument was consistent and to get into a repeatable flow. Here’s my findings-

First the 2 control groups, the Lehigh Defense selections-

Extreme Penetrator 140gr
.3565, .3565
