Nipple bore diameter.

And… once the channel is clear, load the powder charge but before loading your projectile, rap the side of the rifle near the breech several times in order to settle powder under the nipple. Now ram the projectile home, cap and fire. I wouldn’t drill the nipple, .028-.35 or so is just right.

Make sure when you load your rifle that your hammer is on half cock so when you ram the ball down on the powder it forces air out the nipple and blows out any crud that might be plugging the nipple hole.

OR… clean the gun!!

I'm talking about between each shot. Yes the gun should be cleaned before it is shot the first time.

I've been thumping the butt when I load and it's on half cock. I'll try tapping the lock area next.
It's been very rainy here lately so not much shooting going on unfortunately.
