Brass Question

[Bigad 136]

Hi guys been sorting through some brass and noticed some marks on one or too now because I am still a novice I have been only using unmarked brass and sticking the marked ones in a tub to throw I bought the brass once fired so the marks have not come from my rifle would you say I am doing the right thing by discarding it

others may disagree but if it looks ok inside, once its loaded and fired in your gun it will more than likely fire form to your chamber fine and the marks will be gone,the important part is the neck which to me looks good .depends really just how desperate for the cases you are ,ive reloaded worse but you must decide yourself on what to do

[Bigad 136]

Yes the necks all look fine I got a far few so I'll leave them out for now

Were these the Lapua or the PPU ones Ad? It looks like a mark caused by the die if it is the Lapua. If it is the PPU then I would be more inclined to think they came from the factory like that.

Yes lapua only got 3 like that and thought better ask to be safe rather than sorry so far it's looking like 36grn of reloader 15 with a 55 grn v max pill I now got to play with with setting depth I started at 10thou of lands and its groups under a 1p

[Tremo 138]

Mmmm .... that's odd. . I can't imagine what would have caused that line. If it was the die then I would have expected more cases to be the same.

 

1p piece you say?? I bet your smile was ear to ear?? . It is a great feeling isn't it, knowing that YOU made that happen. . Keep up the good work mate.

[Bigad 136]

Yes made me smile will see if I can get it tighter if not still happy will hit what I intended to shoot

[Tremo 138]

You will get them tighter mate .......... I guarantee. .

 

You'll try different powders, primers, seating depths, neck tensions ......... the list goes on! You understand what I mean now when I say that it is addictive eh? :laugh: .

[devon flighter 421]

aint it just

[Bigad 136]

Oh very much so do primers make a difference ? I am using cci and not had a delay or miss fire yet

[devon flighter 421]

yes litteraly everything can make a difference, a shooting friend last week was working a load up and a difference of just 3 th in length of round made a difference of groups at around 7" down to 3/4" all primers have different burn rates "just like powder" and it all makes a difference to pressure and accuracy ,like tremo said its adictive and your now gripped NOW ESCAPING NOW no cure available !

The marks on the case are more than likely caused on extraction of the spent case after firing. Provided they are not deep, they are good to go. Caused by the previous owner's rifle.

 

Sometimes this can be caused when slowly extracting the case from the chamber or crud coating the chamber making it tighter than SAMMI spec

Those marks will be gone after the first firing. Load away

[Migmac 1]

I would say that the marks are made when the case is ejected, I would still use them.

maybe made from underloading cartridges in magazine ,as the bolt travels over cartridge,maybe it damaged case
