Shoulder bump problem or no problem?

[Tidesloe]

Ok so .002 shoulder bump your case web isn't moving?

No, web doesn't change at all. I didn't write it down but bumped .005-.006 is about where I measured that area to be .552. It started at .550 new.

From what i see you need a another die.. if you got like a 28 or 30 nosler sizing die similar try sizing in that then your die too bump shoulder

Maybe the die is the problem?

Yea sorry I replied before I saw this, and I do see that the die may be the problem

IIRC... the reamers .200 line is around .553-.555. That possible bur that gouged the case at the .200 line may be your problem.
It doesn't take much to get tight in that area.

if its .553 or .552 at datum and its not sizing at all until you bump the shoulder.008 then it is a die problem.

I'd like to get a reamer print on it. I think 2 companies make a reamer, but off the same print. There aren't multiple reamer dimensions on this one. The SS and Max there are 2 different reamer dimensions, but not on this one there isnt

If reamer is .553 then you want case sized too .550

I believe, I'm gonna agree completely on this. That's why I come here for some knowledge.

You have a 30 or 28 nosler die too try

Which dies are you using? I replied on the .338 Mega thread, but I have no problem chambering my fired and sized brass (0.002" bump). My barrel was chambered by Preferred Barrel Blanks using the long reamer (rented for this job).

Hey there Handgun. I'm using the Hornady Match dies, and I was chambered with the long reamer. I think I'm wondering if I have that chamber cleaned up and what seems to be a burr gone, would I still have the die problem?

No I don't.

Did you measure your neck diameter near the shoulder?
I'm doing the same thing, but I'm going from 7mm to 30 cal. I found that using Lapua brass instead of Peterson brass that after resizing a case after fireforming The neck diameter near the shoulder junction is significantly larger and in a lot of cases larger than the neck in my chamber. I sharpied up that area and chambered the case, with resistance, and there were no identifiable marks in that area. That measures larger. I did find that there was a very, very tiny thin ring at the shoulder junction where it seems the shoulder junction in the chamber is hitting the case. This happens even though I've bumped the shoulders back. 0.003. so, its almost like the donut exists in the neck/ shoulder junction area as well and shows up when I size the case.
I'm not sure what to do about it other than neck turning or honing out the rear portion of the neck in my chamber

That would be a tough one. I suppose something like that could be going on. Like you I see no marks in that area after I've sharpied my case. I'll measure it and see what I've got. This could also be a possibility.
