I've just finished loading a selection of .223 blanks with the hornady blanking die and various loads of 2206h using 205m primers.
These were for a can cannon.
I started at 20.0g and loaded up in increments to 26.0, all had the same result, a little 'Pop' and lots of unburnt powder.
Any ideas what I'm doing wrong?
Cheers

Not enough pressure to hold the powder in? The primer is blowing the powder out instead of igniting it. Can you put some dacron on top of the powder to hold it down against the primer?
With the 26g loads the case is full
As per Stug. You may also find rifle primers are not helping your cause. I had a problem loading my 32/20 - unburnt powder present in the barrel. Even with crimping this occurred. Changed to a pistol primer (less ferocious blast) and much improved. Your powder selection may also be an issue. There is a member of this forum that loads blanks. He may come fwd with his view. Sorry, cannot recall his handle.
@7mmsaum loads for net guns I'm sure he'd have an idea.
I suggest a faster powder such as a shotgun or pistol one. Blank requirements are totally different to projectile loads once the crimp has opened the pressure needed to keep it burning is lost. A super fast poeder like red dot or 700x should work. I have no suggestions on amounts but nowhere near a full case. Some 308 blanks i disassembled years ago were only bout a third full and the powder burnt bout as fast as gunpowder woosh! Smokeless requires pressure to burn is different to

Needs fast shotgun type powder

Trail boss works for blanks also.

Cool mate, when I spoke to you on the phone you said 2206h would be good for my 308 net gun loads?
With the .223 ones I'm doing now I want to fire a 350-400gm weight further than I am at the moment with m195 blanks.
Should I be using pistol primers?
I'm at the airport heading to work for a few months but I wouldn't mind getting all the info I need before I come home.
As usual on the forum the help and knowledge base is flowing, thanks guys.

I did say trail boss but you did want a hot rod load
I thought you needed a blank firing attachment to get a decent bang? It basically restricts the muzzle to a tiny exit hole.
And creates enough back pressure to cycle an auto for eg a Steyr AUG
:useless: of the intended end use......
