Martin-

Each of my forum posts shows two targets I've shot with a couple of my double rifles.

The image in my signature line is of my J&W Tolley 450 magnum express double rifle, two live rounds, and the two fired pieces of brass from when I finally got it 'shooting'

If you right click on my ID avitar image then click 'view image', you will see an enlarged view of that avitar.
That's a photo of one of my sixteen bore double rifles, it's first day out shooting in likely well over 100 years.

Those two hits on the lower left of the target backer were 'a quick pair', the first two shots from the rifle that day.
I took aim below the paper target at that area, nailed the front trigger, quickly regained my POA then the rear trigger, broke the gun open and removed the brass.

That was a relatively glorious moment, as I'd had to go through a fair bit of work to get to that point - casting chambers, making brass, researching appropriate loads, developing wads - components - loading tools...

The shots rang at about 7:00AM, there was a low blanket of thin fog over the old dry lake/shooting range at the ranch.
I got up to walk down to the target backer for a look, cracked a grin, and broke into a low laughter as I walked back to the bench for a few more rounds.

There was a 20-30 yard long, ten to fifteen foot high and wide billow of blackpowder smoke slowly curling into itself as it rose above the thin layer of fog.

That was a good day.
