I’ll absolutely be testing different seating depths, charge weights and even powders at some point.
The brass prep testing is just a quick and dirty one and done type test to kick it off.
My current fired brass prep is..
De-prime
Imperial Lube case
FL size
Wipe off lube
Bush/moly necks...
Absolutely. I’m also curious to see when I repeat things with once fired brass. The case filling the chamber and getting the carbon in the necks definitely adds a level consistency, but I’m definitely want to see what that difference really is.
Also I’ll see if I can shrink that group with any...
I have carbide for every caliber, but they only come in one size that I’ve found (.001 under caliber I think?) And I like a little less neck tension than they provide in most cartridges.

I’m not the most savvy on the video/youtube stuff. But I took these videos last night and just combined them with an app I downloaded. But the app makes the view more narrow unfortunately.
You know that’s a damn good point about most of that additional seating pressure coming more so from the dry neck, than the case not being mandreled. Thank you for bringing that to my attention!
Just brushing the necks with an oversized nylon brush on a drill helps immensely. That oxidation...
That’s exactly what I’ll be doing as well. I’ve been down this road before haha. I did this one for the people, so they can see for themselves why I prep it how I prep it. It may not even show up on target. But I can see the difference and I can feel the difference. And I don’t like it. Whether...
That’s pretty much every brand also. They are all undersized quite a bit. It’s not even worth finding out IMO, although they “felt” like they seated with similar pressures. Just plan to mandel virgin cases every time IMO.
I just made a video mandreling the virgin cases without brushing and...
Prepping the next test.
I’ll be focused on verifying drop data with the tumbled pieces, and monitoring velocities.
The “no prep” seated with substantially more force (which I expected) and left a small dent in the circumference of the bullet.
I’m absolutely interested in and will be checking those things as well!!
Absolutely. I’ll do a “once fired” test day with lots of different tests on the fired brass! And will test that as well 👊🏼
Absolutely a great and easy test to do in the future with fired brass. It will happen 👊🏼.
Thank you! I’m looking forward to the learning and sharing as well!
Habit and bore scoping mostly. Most barrels grab a shit load of copper in the first 10 rounds. Because the bullets are getting scarred by the edges of the freshly machined lands and then deposit a ton of copper. I’ve seen this 100% is several barrels.
Once that initial copper is out, it looks...
Oh good question!!
So this is my initial baseline preferred way of prepping virgin brass.
1- chamfer inside and outside of neck.
2- brush inside of neck with oversized nylon brush on a drill.
3. Moly lube inside of neck
4. Mandrel with a .2235 mandrel
I’ll be testing the brushing...
Sure thing. Intentional velocity readings every 100 rounds or so will be a piece of cake.
The rifle has 48 rounds on it now, and the barrel is scrubbed clean. So it’s been cleaned twice now. I don’t intend to clean it again for a substantial, but undetermined amount of rounds.
What I’m calling the 22 creedmoor project, has started.
