I measure with the 21st Century tool which shows near 0 runout on my gage pin.

Can you explain how you get those results?

Yes, I resize every case in the coax press. Then I use a lee Collet die for the necks. I give 1/2 turn then size again in the collet die on my first stage of my Dillion Press.

I have used a neck expander die in stage 1 and had similar results but Im currently using undersized mandrel to increase neck tension a bit in the Lee Collet.

I was using a Lee sizing die with the expander ball removed but on this batch I used a RCBS Small base sizer die with the expander ball. and I had 1 rd that was around 2 thousandths the rest were around 1.

I was very impressed with the RCBS Die.



I will try to PM a video

Akinski….

Thank you for the videos. I don’t think we are comparing apples to apples. That said, thank you for sharing your methods.

Nathan,

Your welcome.

One thing I did notice with most resizing dies that have an expander ball is that it did pull the necks off axis. I learned that from this forum.

I did several tests removing the expander ball and it helped. I did find lubing the case necks both inside and out helped alot in reducing runnout from the expander ball.

But the best I could ever achieve using only a resizing die with an expander ball and lubing the necks and a coax press was nothing better than 2thousandths runnout.

Are you using an expander? If so, who’s?

[akinswi]

The videos I sent you I used a RCBS Small Base Resizing die , So I was using the expander ball that came with the die. Then I used a Lee Collet Die to square up the necks.

But I can achieve same results with removing the expander ball. The reason I left the expander in the die is when it is removed the necks are undersized quite a bit , So when I size them with collet die, it takes more lube for the mandrel to be inserted in that case neck.

My runnout didnt get better or worse so I left expander in this die.

I run without expanders and run the cases through an M die, works great, I hate that pull on the expander balls.

I do keep a small cap of lube next to the press and dip the necks into it when I feel a bit of tug on the M die and that is good for another 3-5 cases though I tend to do it every 3.

I just got an RCBS Match bullet seater for the 6.5 x 47. Love it. Back when I built the 6.5 I could not find one, 6.5 x 47 is a bit of an undeserved market and for good reason, its not nearly as popular as 6.5 CM.

Biggest issue was when I found there were NO large primer cases for 6.5 x 47, and I was running out of small rifle primers. My brother bailed me out with some 1000 boxes of CCI and I have been able to get a few of the 100x 3 times now and I am holding my own with primer stock.

Lots of large rifle primers and I have a 6.5 CM barrel if I need to shift. Powder is harder to get but I have a good stock of it as I buy in 5 or 8 lb jugs if I can now.

RC20,

I love my M Die and it works well. Im just tinkering with the undersized lee mandrel to increase neck tension just a wee bit and see if it improves my scores. I dont shoot groups anymore just scores. If it helps me hold a 10 ring and increase my X rings im all for it. If it doesnt will go back to my old setup

Sorry To OP that this thread went down a rabbit hole
