ORIGINAL: Semisane
ITEM - In my first try with Blackhorn in the Mustang using a .25 ACP breechplug and small pistol magnum primers I had delayed ignition on every shot and several failures to fire.
ITEM - In my second try using a 209 breechplug and CCI 209 primers I had failure to fire with the first two primers I popped. The firing pin broke on the third try, ending the test.
ITEM - I've fired 15 shots with Blackhorn and CCI 209 primers out of the Omega X7 with no ignition problems.
FACT: The Omegabreech plug is slightly
longerthan the Mustangplug. A very small difference, but still longer.
FACT: The flash channel in the Omega breech plug is a lot
smaller than the flash channel in the Mustang plug.
QUERY: What the heck is going on?
Here are the two plugs - Omega on the LEFT, Mustang on the Right.
So, I got curious and did a little measuring. The measurements shown in the (amateurish) diagram below may not be exact, but they are pretty close.
Note that the flash hole on the Mustang plug - though almost twice the diameter of the Omega plug - is almost
four times longer.
Now I'm wondering if I'll ever get Blackhorn to work well in the Mustang. Hey, maybe that's a good thing.
If you look here:

and look at these Breech Plugs on page3 of the brochure your BP looks like it should work to me:
To me yours should work according to the pictures I see. I am going to ask you to do the following:
1) switch to some Federal or Winchester Primers and see if your problem goes away,
2) make sure your sabot is verytight, you should NOT be able to push it down with 1 hand
3) I wantyou to put your full weight into the ram rod once thebullet is down on the charge.
I had these EXACT same problems with my Savage the first time I shot it and I was NOT compressing the charge tight enough.
