I tried it but I think I suck at this method. It ended up sub 3”. Hahaha.If you’re concerned the case might not be seating properly, just take a fired case and deprime or drill the primer out. Then I just put some loctite in the case neck, start a bullet in and gently chamber it. Close the bolt and wait a few minutes before extracting. You’ll know for sure then.
This Frankford Arsenal OAL Gauge is pretty handy and consistent within a few thou once you get the feel for it, also measures from the bolt face so it's a true OAL.I tried it but I think I suck at this method. It ended up sub 3”. Hahaha.
There wasn’t enough neck tension so even just getting it chambered as gentle as possible it slid back. I need to try again after bumping the neck ever so slightly with my sizing die to just give it the slightest bit of neck tension.
Interesting piece of gear. I might have to try that.This Frankford Arsenal OAL Gauge is pretty handy and consistent within a few thou once you get the feel for it, also measures from the bolt face so it's a true OAL.

It does if it needs to fit a specific magazine length like most of my rifles.I didn’t think seating depth mattered![]()
Still yet to see valid proof that it does for precision, but it can affect pressure. And I need a baseline measurement to track throat erosion.I didn’t think seating depth mattered![]()
Valid proof is found by the individual reloading for themselves. No one could possibly prove it to another person like you cuz you’ll just say anecdotal evidence is not proof.Still yet to see valid proof that it does for precision, but it can affect pressure.

There are statistics behind the sample sizes and variability, it's well established. I haven't seen a significant data set that proves an outlier. Feel free to post your anecdotal evidence in my 18 page thread about the topic.Valid proof is found by the individual reloading for themselves.

I adjust seating depth for every rifle but some rifle barrels respond more than others.
Want proof for yourself? Buy an old K98 and load 175 grain bullets and see how well it shoots and then start seating the bullet farther out and watch the groups tighten up.

The cleaning rod OAL gauge is a cheap and effective tool for finding the distance from the bolt face to the lands, using a comparator. It's great for tracking throat erosion, or adjusting seating depth, if you so choose to do so.

That a 686?View attachment 971680
First batch of 10mm Magnums. Hoping to shoot through the ladder tomorrow if weather permits.
610, N-frame 6.5” barrel. It’s an early pre-lock pre-MIM gun that the previous owner had the cylinder reamed for the mag cartridge.That a 686?
