I am trying to work up a load for 75gr Amax bullets in my Savage 12 LRPV 1:7 twist . I get
a ring around the brass , just under the polymer tip caused by my seating die . I have tried
both Lee and RCBS Competition seating dies but both leave a similar ring in the brass . This
must affect accuracy ? Anyone else had this problem ? I am shooting .223 .
 
depending on how accurate you are trying to be it shouldn't effect accuracy much, none if it's just plinking.

what you can do to solve the problem is either send a couple bullets and the seating stem to lee and they will machine it to fit the profile of the bullet or use a hot glue gun and put a blob of it in the seating stem and push one of the bullets into the seating stem as straight as you can get it so it forms a temporary mold of your bullet. depending on the size of the seating stem you could use a tube as close to the size of the bullet diameter but will also fit onto the seating stem and use that as a guide to keep the bullet parallel with the seating stem.

hopefully that makes sense.
 
The bullet is copper but this issue is common with low drag bullets in traditional seating dies. Or more specifically the seating plug which was resigned to work with the general gamut of bullet designs. The ring has no effect on accuracy but seating that far up the bullet usually causes more variation in seating depth as measured base to ogive. The solution is a seating plug designed for high BC bullets like the AMAX. Lee's custom shop will make you seating plugs to fix the issue and most match dies use a seating plug designed to reach the ogive of such bullets.
 
Or you can ream the seating plug to a larger diameter followed by a bevel and polish.
I noticed the ring on Hornady Match 75gr but these bullets have no lead in the nose.

I reamed the seater to a diameter that pushes on the lead filled area of the ogive. I used drill bits for reamers.
The Lee seater steel is soft. Took a bit of metal at a time and then spun a bullet in the seater to see where it makes contact. 4 iterations and I was done.
 
you could just get a forster benchrest competition die which is made for this shape of bullet and will seat your bullet with less runout improving accuracy

Thanks for all the fast replies . I have not seen these rings on any other bullets I use in 223 . I don't shoot 223 much for targets .
I have a 222 , 6BR , 308 and 260 that I load , but I have Forster dies for them , and this ring thing has never been a problem .
I will check with Lee custom and see what they can do for me . I will set up the Lee die for the 75's exclusively if it is not expensive
or order a Forester mic seating die if that is less $ .
Thanks again for the help .

The Forster BR dies are McF*ckin Mint.

+1 on the Forster!!! I'm an absolute rookie/novice reloader, and I average less than 0.02" runout using my Forster Ultra Micrometer seating die. The stem fits the profile of the Tipped Match Kings almost perfectly and makes just the slightest rub/mark on the bullet. Certainly no deformation or pronounced ring...
 
I had the same issue loading the 129gr Accubond in my 6.5x55 cases, with my Redding match seater die. I changed out the seating plug for the VLD seating plug, and the issue was resolved.
 
IIRC custom plugs are around $4 USD each plus shipping. A Forster BR seating die is similarily priced to a complete Lee 4 die set. I may have to order some too now that I want to try the 75 gr AMAX in my scout.
