I'm having trouble with misfires when using the new blackhorn powder. I decided to try the new blackhorn powder in my 52. cal disc xt (standard domed breech plug, win 209 primer) but can't get it
OK
The problem is the domed plug. And here's how to fix it:
find the drill bit that just fits the inside of the nipple. Then drill out the plug
Exactly 5cm--that is measured from the face of the nipple. This will end just at the beginning of the bare--non-threaded portion of the neck.
Now you will have a plug that still resists blow back, and will ignite BH209 Every Time.
I know, cause that's how I got mine to work flawlessly
And use Only
NEW red plastic jackets, and this will decrease blowback even more
