You said one didn't go off at all? Are getting good firing pin strikes?

If the case base to datum was too short, I should also experience this issue with other powders. I am going to tear apart the failure to fire and inspect the powder and primer. The firing pin indented that primer like it does all the others.Pro Varmint is in the burn rate are below W748 and above IMR4895.
While I know burn rate is not specific, it does tell you what general area the powder is in and you can cross ref to associated uses.
As noted it seems like one of a number of issues. Case size is suspect (too short on the shoulder) as a hang fire and no fire can be symptoms of a case giving way as it is hit by the firing pin.
I did mean a 3/32" bit. Thank you for pointing out my mistake.Kilo a 3/16 bit is .1875. 1/16 =.0625. Or do you mean a 3/32 bit.
Yes, it has been clumping. I thought it was just because it is such a fine powder and it sat for a few years. I will throw away that pound of powder and try the next pound. I have four pounds of this powder. All from different lots.BLC2 is not particularly easy to light. If you have no problem with lighting it with your current flash holes, then I suspect the powder. If you have a kinetic bullet puller and some loaded 308 ammo with large primers, you could also pull a few and dump the powder and substitute yours and your bullets. If they have the same problem or have very wide velocity variation, it is definitely the powder. Powder has a number of failure modes, including behaving as you describe, though it is often clumping a bit by then.
I originally purchased this powder for 6.5 Grendel. I have been using it in 5.56x45 for a while. In fact, I have around 1000, 69 grain Sierra Matchkings loaded with Power Pro Varmint. I have had no issues with the 5.56x45 ammunition, but like I said earlier, most of the bottles of powder I have are from different lots. This bottle of powder had not even had the seal broken until I opened it a couple weeks ago.you have any other calibers you can try that PPV in? It has a good rep in .223 and 6.5 Grendel. My money is on contaminated powder
I do not have a single large primer 308 case. It might serve me well to buy some. Although the rifle is shooting well enough and my load with Varget gets less than 20 fps extreme spread and around 5 fps standard deviation.BLC2 is not particularly easy to light.

I don't have any .308 Win that takes small primers (nor any .45acp that does, either). Don't know where to look, not interested and wouldn't accept any as a gift. IF there is any benefit to using small primers in .308, I don't know what it is, and I doubt it would apply to my guns and my shooting….
Then, as to the claim that SRP ‘Palma’ cases reduce MV ES (extreme spread) values compared to their LRP brothers – the reason for the American Palma teams asking Lapua to produce the cases in the first place – the weight of evidence based on actual range experience and competition results is so great that few if any will question this now.
