Hi,
Im back from the range.
I have been shooting my spanish double shotgun.
It have a 2.5 scope on the band. Cylinder right barrel and .690" left one.

I use a couple of shots to set the sight and this is a 3 shot group with "Stoping Power" ammo from right barrel. This is the slug usually called DG or Dangerous Game, made in Italy by Gualandi.
Three shot group in 7cm, lees than 3". I pull my second a little low so it can shoot better.

Then tryed two shots from left (choked) barrel. I asked Gualandi if I can shot them thought a choke and they answer:
"Following your today’s kind Inquiry, please be informed that our 12 Gauge 32 gr. Borra-Proiettile can be shot through any chokes, while our 12 Gauge 40 gr. Borra-Proiettile can be shot through barrel cylinder only."
Only one of the shot lands on paper but much to the right and a little high.
This can be a problem as I plan to use this gun a a double rifle.

Also tryed the Winchester Slugs from right barrel:
Four shots into less than 3" too.

Finally tryed some local slugs but the do not work.

Next time will try some round balls I have (.715") as Im waiting for a Tanner mold that is coming from England.

Thanks
Martin

Edited: all groups shot at 50 meters (55 yds)
