What did you do in the reloading room today?

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.
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.
 
308 w/ 168gr eldm for deer season, 45/70 subs and supers. Also worked on some homebrew subsonic 450 Bushmaster I came up with that cycle an AR (resized 405gr cast lead from .458 to .452). That's been an interesting journey, but they stomp up close on deer or hogs.

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.
 
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.
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.
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.

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.

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.

Started reloading long before any gauges were around.
Get a K98 like said or a M1917 and see what happens. Both like longer seating.
My savage 110 likes a 150 gr sierra pro hunter seated deeper than Sierra recommends.
So keep your stats cuz I know what rifles like.
Not the best pic but it gives you the idea but it won’t satisfy you naturally.IMG_0474.jpeg
 
Resized & trimmed some Federal brass & nickel 06 cases.
I have been using Federal Premium 180’s (in photo) that were gifted to me.
The thick woods I hunt and the 35 yard shots, the premium ammo is causing too much blood shot.
Real mess of jellied blood to clean when butchering.
Going to load Sierra 180 RN behind Surplus 4831 & W748 to lower velocity & the RN will expand less.
Which ever shoots better I’ll go with. Next year I’ll see if it helped.IMG_0508.jpeg
