Is it even a slightly compressed load?

Good question.

This isn’t the right bullet, but for interest’s sake anyway:

Note that for this particular bullet, the OP would be 9 grains over Hodgeson’s published max load, and even the 81 grains is a compressed load. Note that his coal is .200 longer than published here, but I expect that may have more to do with the length of the high bc bullet, and not actually mean the base is .200 higher in the case than the bullet listed above. Looking at that, I’d wager that it’s a significantly compressed load...
 
I agree - info given makes me think the compressed powder is pushing up the bullet.
To verify, load some dummy rounds, no powder, and see where they come out.
If still wonky, seating stem would be the next item to look at
 
Likely the seating stem, next thing to do is sell everything and take up knitting. Less frustration and you could sell mittens to reloaders for cold weather shooting. :p

Finally someone with some sense ;)

I would venture it’s the stem after doing some thinking.my reasoning , I have run much more full cases where you can feel the kernels crushing , also I’m below , at and longer then my desired seating depth and i cannot feel the case touch the seating stem when I run the case back up the ram a second time , even when changing dies.

I shall head out shortly and try a few things and report back.

ah, well .016" isn't that much variation if you're basing cartridge base to tip. An ABLR should be using a VLD/ELD seater stem

The bigger problem here is the load is much too compressed. Bullet doesn't have a chance to seat consistently as its being driven down into the packed powder charge

8 more , Speer 180sp.

3.472” And 3.472” the Last 6 were 3.475” to 3.477”.

Apart come the dies , again , see if I can drill the seater out at bit at the point.

I think it’s gotta be your bullets. Slight variations in the width where it’s meeting the cup. Depending on the angle where it meets, a difference of .001 could allow the bullet to enter ten times that amount further into the cup.

Excuse my crude cell phone drawing.

But here is the question , how are they seating long and staying seated long ?

I even tried my other press to rule that out.

Bullet length tip to base varies only a maximum of 0.004” , average was about 0.002” which I feel is acceptable.

Maybe I’ll load 20 dummy rounds and take it from there.

I know it’s not a factor but I may just start from scratch with new brass also , I don’t like how the primers don’t sit flush in the hornady brass.

Okay, think I have everything that folks wanted for info.

I thought I was off to the races thinking Todd was right on the money, but as I kept measuring , things went sideways again.I'm a bit concerned about a 0.020" swing.

Here are the measurements of 20 dummy rounds(not dummy round because a dummy was loading them).

Also measured 10 random bullets.



Here is 80 grains of H-1000 in my case...



Here is the level in relation to the case...



Here is the relation to bullet , depth and charge level...



Here is NOT what was in my reloading room distracting me, then I'd have an excuse...

I would guess ... too much neck tension.

If you have a way to adjust the neck sizing, go with a net 1 to 1.5 thou squeeze after it comes out of the sizing die.

If the sized brass has upwards of 3 to 5 thou neck tension, that is likely the problem... plus runout may not be ideal either.

Finally, you may have donuts at the base of the case neck which affects the depth the bullet can travel in. Expand with a mandrel and outside neck turn.

If the brass has been fired a few times, anneal the case necks as well.

sounds like a neck tension issue.....

I did turn and anneal, I took about 60-80% off the surface, I'll measure with my caveman methods and see what kind of interference I have and if they need more thinning.
