craigyboy Posted June 20, 2007 Report Share Posted June 20, 2007 my seating die seems to leave ring mark around the bullet. Any ideas what is causing this? Link to comment Share on other sites More sharing options...
Guest 308Panther Posted June 21, 2007 Report Share Posted June 21, 2007 We just went thru this on another board I belong too.... Think it was the amount of powder/compression when seating that caused the problem.... 308Panther Link to comment Share on other sites More sharing options...
Guest varmartin Posted June 21, 2007 Report Share Posted June 21, 2007 I get the same thing seating 60 vmax and 75 amax in my 223 reloads, both are near or compressed loads. Never made any difference to accuracy though. I use redding comp dies and this happens ?? I put it down to lightly built bullets and a full case Dont get it in my 6 MMBR.

ejg223 Posted June 21, 2007 Report Share Posted June 21, 2007 Had the same ring, which is quite sharp and narrow. It can only be the edge of the die that gives the mark, what else? If one polishes the edge a bit or puts a tiny radius on, it should be better. edi Not a great pic of a Lee 223 die. Untouched, sharp raggy edges. After a bit of polishing. another bad pic Link to comment Share on other sites More sharing options...

Toby Posted June 23, 2007 Report Share Posted June 23, 2007 I have got Forster BR die sets in 222 and 6.5x55.Both seater dies leave a tiny ring around the bullet,even when its not a compressed charge.Haven't done anything about it as it doesn't affect accuracy noticeably.cheers Toby Link to comment Share on other sites More sharing options...
stag1933 Posted June 23, 2007 Report Share Posted June 23, 2007 It is the seating plug at the top of the die which causes the ring. It has nothing to do with the bottom part of the die. If the shape of bullet ogive is different to plug shape a ring will appear when the bullet is seated. This is insignificant when compared to what happens to the bullet as it it is squashed and forced along the rifling by gas pressure. Too much importance is given to such insignificant details. Human errors are the cause of most poor shooting. Link to comment Share on other sites More sharing options...
ejg223 Posted June 23, 2007 Report Share Posted June 23, 2007 Stag you're right, but i like to keep my tools in order, so i'd trace that and fix it. Another thing, airfoils are sometimes depending on their shape very critical on imperfections. For example, high performance airfoils on gliders can turn to real low performers if covered by dead flies or a bit of dirt. That's why they polish those wings like hell. On the other hand i took notice of really bent sp tips that shot just as well at 100yds on paper than the ones that seemed perfect. edi Link to comment Share on other sites More sharing options...
Guest steyrman2 Posted June 24, 2007 Report Share Posted June 24, 2007 hi when i started to load for the 223 using redding comp dies every one of the heads had a ring around them but after a few thou heads its has sorted it self out i tought i was a fault and rang norman clarkes the said it might need to be polished out but i left it at it was did not effect group size very happy with redding dies have them in 308 as well and no problems Link to comment Share on other sites More sharing options...
millpool Posted June 24, 2007 Report Share Posted June 24, 2007 hi get the same thing on my 223 loads,using reding competition dies and either nosler ball tips or v max,i thought it was just me! Link to comment Share on other sites More sharing options...
stag1933 Posted June 24, 2007 Report Share Posted June 24, 2007 Hi edi. I would not worry about distorted soft points on bullets either. Some years ago Speer showed a photo of a bullet in flight at less than 50 yards with the point already melted off. After this I did a test and damaged points on purpose but did not see a deterioration in group size or shape. Link to comment Share on other sites More sharing options...
Ronin Posted June 24, 2007 Report Share Posted June 24, 2007 I had a similar problem with my Redding seater die for a .257" Cure; take the seater die apart, obtain some polishing paste (valve grinding paste is good - the smooth variety), mount the seater stem in a drill, and use a few sacrificial bullets dipped in grinding paste to "polish" the seater stem ogive to the same as your chosen bullet, it takes a little while and you may waste ten bullets but the effort is worth it. Dont forget to use a little light oil to lubricate the paste. If you are using redding dies spare seater stems can be bought and polished to suit all the different bullet ogives you use.

Stag i had one thing i couldn't explain, on paper my 223 would group way better single fed out of the mag than sticking a couple rounds in the mag. At first i thought the tips were bent from that 'massive' recoil?? but maybe there is another reason. Maybe it was just me. It seemed the same with sako SP 55g and cheap 50g fed hp. Didn't appear as much with hornady plastic tips. ??? edi Link to comment Share on other sites More sharing options...
stag1933 Posted June 24, 2007 Report Share Posted June 24, 2007 Hi edi. I have noticed over the years that the lead points of bullets HAVE been battered in the magazine but I have never bothered about it as they kill the deer with no noticable difference to the first which I drop directly into the chamber. My Carl Gustaf .270 work tool has a couple of 3 shot mags., so I always drop one bullet into the chamber to give me 4 shot initial capacity with 3 shots to follow from the other mag. If I wanted to drop 4 or 5 Hinds and calves out of a group I had enough in hand so to speak. With all things however, whatever seems to work well for you stick with it. I only believe in change when I see a material benefit. Link to comment Share on other sites More sharing options...
Andrew Posted June 24, 2007 Report Share Posted June 24, 2007 I agree with those who dismiss that ring. My Hornet dies do it and I still get half MOA. My 7x57 RCBS dies have done it for years and it's one of my most accurate hunting rifles. I will screw up a shot long before the dies cause me to miss!~Andrew Link to comment Share on other sites More sharing options...
Zaitsev Posted June 25, 2007 Report Share Posted June 25, 2007 My 6ppc redding comp dies leave a ring too. Latest best group off a bipod with an informal rear rest (binos) was .096. Don't think that ring makes a whole heap of difference. Cheers Z Link to comment Share on other sites More sharing options...
