Si-Snipe Posted November 2, 2011 Report Share Posted November 2, 2011 If brass is frequently annealed and prepared well. How long do you guys get from your cases before you notice drops in accuracy? Has anyone ever run tests on this? I'd be very interested to know the results. Link to comment Share on other sites More sharing options...
1967spud Posted November 2, 2011 Report Share Posted November 2, 2011 im using .243 ackley brass thats at least 9 years old and had 25 + firings and as long as i anneal now and again and keep a vigilant eye for defects i cant see it getting any worse Link to comment Share on other sites More sharing options...
rabbit fingers Posted November 2, 2011 Report Share Posted November 2, 2011 Did you neck turn them? Have you had to remove do-nuts? if so, after how many firings? don't want to hijack the thread but very interested too. Link to comment Share on other sites More sharing options...

taylor Posted November 2, 2011 Report Share Posted November 2, 2011 i got brass that has 15-16 firings and still like new but annealed every 3rd firing i bin when primer pockets go to slack Link to comment Share on other sites More sharing options...

taylor Posted November 2, 2011 Report Share Posted November 2, 2011 spud if you run a tight neck then 2-3 is good enough - ,i tryed my own little test over crono and 2-3 firing their was no shift in es and sd ,on 5 firing es and sd nearly doubled but group size was nearly the same ,so why waste gas ,but every person likes to do things diffrent if i ran a factory neck then maby every firing might help if you aneal regular and with right temp with a decent machine it will be consistant and uniform if you under aneal then it wont Link to comment Share on other sites More sharing options...

Guest richness Posted November 3, 2011 Report Share Posted November 3, 2011 I've spoken to you about this privately but i'll air it here for discussion too Si mate: My experience with brass is that it lasts well in match chambers and with regular annealing. And if you don't go mad, the primer pockets don't prematurely kill the brass. Yet after a while it just goes off and accuracy goes off slightly without any other signs. Eg, with my 204 i got to about 15x and I happened to buy some new brass and whilst zeroing shoot the old and the new alongside, with no other variables. The new brass groups were very significantly tighter than the other older brass was. I was shooting at 150y with my latest and tightest load. The new brass was practically a single hole whilst the older was a perfectly decent little cloverleaf. Not a big thing but everything is a big thing . Not a matter of less flyers or anything, just simply tighter across the board. This reminded me of something baldie said to me once when I was admiring his annealing machine "you can keep them going consistently for ages by annealing but there comes a point when they just lose their spring and you need to bin them all and start with fresh brass" It is quite a long time though, and it depends on the cal, i'm sure. I recently compared 9x brass to 2xbrass in 6.5x47 lapua and there was not a jot of difference. But i am alert to the fact that if things just start sliding gently sometime around 12x i will try new brass (but it may be 20x in 6.5x47 - i don't yet know) Link to comment Share on other sites More sharing options...
