BLC 2 ignition/hangfire?

[migrant hunter]

I have been handloading for about 4yrs, started off with BLC2 as it was listed for 308 and 243, and was readily available. I was getting hangfires now and again at first, just a barely noticeable "clickbang". I put this down to not having primers seated fully or tight pockets. It eventually seemed to go away.
I moved on to Varget and Reloader powders, with good results. I have been unable to get Rel 19 for my 243 lately, so I went back to some of my old recipes and tried a few loads out today. One of the loads was with BLC2, and out of the 9 rounds I fired, 3 had minor "clickbangs". All rounds were loaded with CCI larger rifle primers, which is all I have ever used. It was"nt cold out, and all other rounds(Varget) shot fine.
Has anyone found BLC2 slow to ignite, or is it my imagination?

Maybe an obvious question, but are you using magnum primers? My manual lists blc-2 as needing magnums...

I've used fed210 and have had no issue with hang fire even on full house rounds 308win. Maybe try a different primer.

it's ball powder, therefore , magnum primers-so says the holy book
