It's a bushing neck sizing die, I'm using the rcbs concentricity tool. The necks are turned to a consistent .014". But with the bushing it should squeeze all the inconsistencies to the inside and not register neck thickness variance on the concentricity tool

I'm measuring runout and am not using an expander. It's just weird that if I put a case with low runout through my neck sizer it comes out with high runout, but when I put a case with high runout through the sizer it comes out with very little runout...

so I'm resizing once fired brass in an rcbs press with a gold metal match bushing die. I was getting bad runouts after neck sizing so I tried floating the shell holder and got some odd results, see below; Case 1: ro before .0015 after .0075 Case 2: ro before .001 after .00125 Case 3: ro before...

Thanks, that was what I was wondering about.

Yeah that makes sense, I guess my question is that all things being equal if I have two pieces of unfired brass both of which have .0015 neck wall variance but one round has .005 runout and the other has .001 runout wouldn't the cutter cut way too much brass off the "high side" of the piece with...

Would it be ok to neck turn unfired brass that has a neck runout of around .003-.005? The neck wall thickness varies by as much as .0015 on some cases. My concern is that the cutter will be removing too much brass because the neck isn't concentric. But maybe the neck turning pilot will keep...

i recently picked up 100 rounds of Norma 7mm rem mag brass. I wanted to do as much case prep to ensure uniform cases. The question I have is that I measured headspace using a hornady headspace gauge and the rounds varied from 2.106-2.109 which is a .003 difference. If I were to trim the cases to...

I really appreciate all of the help I've gotten from this website and I've found it to be a very good resource. I have a 7mm rem mag and I'm reloading with 162gr eld'x bullets. I'm using the rcbs gold metal match neck sizing and seating die set. My runout is under .002" after neck sizing but...

So I found that if you remove the firing pin assembly and the ejectors your bolt has no tension whatsoever and just "flops" around for lack of a better word. This allows you to really get a feel for what the bullet is or isn't contacting during chambering. Here is the link to the video that...

I had a really tough time finding my max coal with this rifle. Have you tried the stripped bolt method?

I just took one of my fired cases from the problem ammo, neck sized it in my gold metal match die without the expander (I was previously using a standard rcbs neck sizer with expander), seated a bullet at 2.685" with my GMM seating die and chambered the round with the firing pin and ejectors...

So what your saying is you think the chamber is too tight in the neck region?

The scuffing is only on one side. I can rotate the case 180 degrees and rechamber the round and the scuffing will stack up on top of the old scuff mark. Fired neck diameter is .314 and loaded is .3125-.313

Do you think it would harm anything to shoot the remaining 20 "bad" rounds I have to get them fireformed and then straighten them out? I was showing no pressure signs at all with the others.

Yes I do mean lead not throat. I will get in touch with my gunsmith to have him take a look with his borescope, I really appreciate your help. At any rate I got my ammo to chamber as well as it did the first 50 rounds...and I was averaging around .75 moa before working up a load so either way...
