115VLD 243AI Loads Check: Bad WLR Primer Alert

[DoneNOut]

115 Berger VLDT
55.5 H20 capacity 243AI brass
WLR
.06 from lands, COL 2.800
1-7.5T 26" Criterion

Blow primers with following:

41gr XMR4350
41gr H100V
41 RL17
49gr N570
49gr H1000

Haven't had any problems with 105 VLD loads yet. I planned to shoot the 115s with the fast twist rare. But so far bummed out.

What brass?
Have you tried H4350?

A4350, 57,000 psi
H-100, 57,099

Lapua.
No, I've got XMR4350. Made in Serbia blend. It's a bit slower than H4350

How did you come up with those loads?

blown primers meaning, loose pockets, pierced by firing pin, or a hole leaking at the edges. the WLR primers are known for blowing a hole at the edges and might not be your reloads just defective primers.

Technically not blowing them I guess, but this above.

All under 60K. Weird

that there is what is typical for WLR, blown out the edge. it is a primer problem not a reload problem. it doesn't matter the pressure i have seen that happen at low and high pressure.

OMG! I just researched the WLR pinhole issue. This is exactly what happens with the defective primers. Geez, just my luck

at least you now know it is not your fault.

 

[VinceMule]

yes, defective primer. If you have them, switch to a cci 250.

Of the powders listed, R17 and N570 are very hot burning powders, hence fire cracking with show up quicker

 

[DoneNOut]

My lot number is on the defective list. I've got 3 badly pitted bolt faces too. Thousand rounds or so loaded. I'm in a Daggum fix.

Are those two ejector stamps on that brass?
