Maidment78 Posted February 5, 2019 Report Share Posted February 5, 2019 Hello all, Just started loading for the .284 win and I have read about doughnuts on necked up brass, I am shooting a 175 ELD-X so the bearing surface will be long and as such I am looking at getting any kit needed to deal with this before it need it. Any help would be greatly welcome. Link to comment Share on other sites More sharing options...
No i deer Posted February 5, 2019 Report Share Posted February 5, 2019 Is your 284 throated for the 175gr ELD X's Is it a tight necked chamber or a no neck turn chamber Link to comment Share on other sites More sharing options...
Maidment78 Posted February 6, 2019 Author Report Share Posted February 6, 2019 Yes throated for the 175, and it is no neck turn Link to comment Share on other sites More sharing options...
No i deer Posted February 6, 2019 Report Share Posted February 6, 2019 If your using a bushing die you don't resize the whole neck which is where the donuts form which helps this . I guess to prevent this is to cut into the shoulder 20 thousands ish with the neck turner so when it's fired the brass will be thinner at that point with its new fire formed internal dimension. You need expand the brass first Don't neck turn it on a resized brass or new unfired brass. Link to comment Share on other sites More sharing options...
jcampbellsmith Posted February 6, 2019 Report Share Posted February 6, 2019 Donuts? There are many schools of thought on this. Ignore them. Ignore them and seat the bullet forward of the neck shoulder junction. As in the post above, neck turn to remove brass from the neck shoulder junction. Use an internal mandrel cutter to remove material from the neck shoulder junction. Just use new brass. There are issues and benefits to all of these approaches. Pick the one that works for you or come up with another approach. Have fun. JCS Link to comment Share on other sites More sharing options...

Completely ignore what I said unless you already have lapua 6.5x284 brass or sell it and get Norma at about £1.50 per case 👍 Link to comment Share on other sites More sharing options...
MJR Posted February 6, 2019 Report Share Posted February 6, 2019 The OP said its a no turn neck. Why would he get donuts? Link to comment Share on other sites More sharing options...

The 6.5x284 lapua brass is terrible for it , i have a no turn neck in my 284 and got donuts on the very first firing. I eventually gave up neck turning to get rid of them and bought norma brass .

sauer Posted February 6, 2019 Report Share Posted February 6, 2019 I have authorisation for .284 but I want just for hunting , plinking....not looking for any extra case prep etc. working with a damn good gun smith last few days on a job and he said just .284 reamer to saami spec ...not tight spec reamer...and no neck turning and should be fine ? i thought key to this was no neck turning ? other wise it would be Norma brass straight off. paul Link to comment Share on other sites More sharing options...
No i deer Posted February 6, 2019 Report Share Posted February 6, 2019 Maybe one of our experts would explain exactly why 6.5x284 lapua brass expanded to 284 will produce donuts and 284 Norma doesn't...! Link to comment Share on other sites More sharing options...
Maidment78 Posted February 6, 2019 Author Report Share Posted February 6, 2019 Thanks for the comments so far, the brass I have is 6.5 Lapua necked up. All once fired as still playing and I have not had any doughnuts yet but like to be prepared. Link to comment Share on other sites More sharing options...

If you PM me your paypal or details I will do the rest Paul. Link to comment Share on other sites More sharing options...

I havnt used it on boar , only from squirrels to deer . After lots of researching calibres the straight 284 seemed to be one of the most efficient calibres in 7mm and a huge range of bullets from 100gr upwards.
