I wonder if the smaller piece of lead/bullet is causing the lower reading?
I don't doubt the hardness from BACO I'm just trying to understand the difference. Did you try a bullet filing it off?
I would bet it’s the Smaller Sample (Bullet) that’s causing it, Out of curiosity I will test a Bullet, I have some that were Casted from the exact same Batch that i sent you, I will Test 1 or 2 of them Today and post back the Results.
I have always wondered about these testers, How accurate they are from 1 unit to another? Is it possible the Spring “Relaxes” over time? As for the Dial, they Shouldn't be a Problem? They are a simple Machinist Dial, These ones are Cheap Chinese Dials, But they work good. Outfits like Starrett & Mititoyo make REALLY nice Dials that would be a Direct fit, and Read identical (VERY Expensive) But i don’t see these Cheap dials as the “Weak Link“ here? But i do question the Springs
