Gauging a dial caliper for reloading (9mm)

calibrator · 12-24-2020, 10:36 AM

Maybe I complicate things here for you by adding this. I don't re-load for pistol, just precision high power centerfire rifle. Knowing how far the bullet "jumps" into the rifling is critical for load development. If the rifle is magazine fed, what will just fit into the mag is usually the limit unless rds are single loaded by hand.

I use this gage by Hornady to determine this dimension;

I have the same Hornady set but with the anvil in addition to the items you show. For Christmas my sons gave me the new Forster set that I like for measuring cases and ogive-to-lands.

For my handloading I keep both a set of digital calipers and dial calipers handy on my bench. Either will get the job done. I don't own a plastic caliper, and likely will never purchase one. Maybe I am just too "old school"!!

The caliper shown in the pictures is brand new but over 30 years old. It's Swiss made (45.00 $ CND) bought aound the time i got my reloading press. I can tell that it feels very thight altough it's slides smoothly. And you have to put much pressure to measure (instructions). I don't know if my caliper will endure but, with what I've read here, I'll take great care when I use it. Thank you all.

Thanks for the link. I'll have to check in that a little bit more.

Thank you again. I've read on the subject a little and find it very inetresting. Eventually, I'll be relaoding for my 7 mm Rem Mag; which is why I bought a reloading press in the first place.
