Chris, I wonder if runout was why those cartridges didn't chamber? If you had runout of 5 thou, even 10thou, the cartridge should chamber. My guess is that you have a sizing or bullet length issue here.
I have used the rolling of cases on a flat hard surface for years and it has worked. You will not detect the difference in a couple of thou but as long as runout is under 4 thou (no visible wobble), it will shoot small groups (not BR groups just around 1/4 MOA). Testing the ammo at 250yds will confirm if things are good or bad.
I demand that my LR hunting ammo dump the rounds inside 1" to 1 1/2" at 250yds. Not BR accuracy but I am not shooting a BR rifle either.
For sizing, consider the Lee Collet neck sizing die. Produces very low runout cases. If the necks are straight, odds are the seating die will not screws things up. If concerned there, the Forster BR seating die is superb. Unfortunately, not readily availabe in wildcats.
At some point you have to be able to monitor your ammo so that you can eliminate things that are causing your groups to be bigger then necessary.
Test firing will only show that something is not right. Being able to measure during the different handloading steps will confirm where problems areas are.
Those were my thoughts exactly when the rounds didn't fit. When I got home I measure every place I could think of on those 2 rounds and some others that did chamber, everything matched within .002.
Runout might be an understatement for what the 2 rounds had, when rolled across the table the difference between the high and low point of the bullet tip was nearly 3/16". The bullet itself had a line (not land marks) about 1/3 of the way around it approx. 1/4" up from the case neck. All I can figure is the bullet itself was catching in the chamber where the case neck ends and the throat starts. That's just a guess though.
I seated 25 bullets in empty cases later that night trying to duplicate what went wrong, but it never happened. I look at it this way , upgrading dies certainly can't hurt anything. I hope.

Ignorance can be treated with education, sadly there is no cure for stupidity.
I am currently engaged in a little experiment with runout. My preliminary findings suggest that unless you have a very accurate rifle, runout of even .006 will not create a noticeable difference in group size. That said, I load all my neck turned 22-250 cases in Redding Competetion dies. All ammo appears to come out with a max bullet runout of .002. Using a Redding type "S" neck die for my .243, neck runout is from .001 to .004. These cases are not neck turned, but have .001 or less variation in neck thickness. On both rifles, a Kimber and a Cooper, fired cases measure just a few ten-thousandths runout. I am using an RCBS Casemaster, but would purchase the Sinclair tool if buying again.
Once I got my Forester dies (22-250, 270, 7mag, 06, etc.) my run-out dropped dramaticly compared to what the Redding & RCBS dies were giving me.
Very rarely do I have anything over a .003 in any one caliber. Some times the 06 cases will start getting the "banana" curve and I might have a little problem there, but that's simple fix....dump the casing.
A casing rolled on the counter top does not tell you the whole truth. A empty case can be rolled and then you can see where the "thin" side of the casing is. I then mark this spot so when I put the casing into the chamber each casing will rest in the same position.
Just one more thing to try and "squeese" a little more accuracy. Some do it - some don't

The dies were the "3 die deluxe set" (have to sets for sale as of now). The main problem with the dies are the "die length", they are to short for my Lyman Orange Crusher press.
The lock ring will only catch the last thread on the die, it makes it very hard to aligned straight. On my 7mag die the "set screw" on the locking ring goes above the threads against the die body......missing the threads completly.
So I sold two sets and have two more to go...all Forester dies from now on.
