Short Stoeger update,
I was able to get away to the range for a short time today, only 1/2 hour to give the Stoeger a quick try.
The chokes were removed to see what the cylinder bores
would do.The 3" loads shot low,about 1-1/2 feet at 25 yards.
Since I only had a bead to sight with it took some luck
and sighting high on a mark I made above the target.I
found the right barrel shot on target with 2 inch. groups
but the left barrel shot 1 foot low to the left giving
2-2 1/2 inch groups.

The 2 3/4's gave much better groups,shooting about 8in.
low but grouping both barrels on but slightly to the left of
target.Four rounds into four inches,2 right and 2 left.

I am going to try some make-shift sights to attach to the
barrels,I may be able to shave an inch or two off that group
if I can actually see the target.

Thanks for the info Daryl S

Here are the slugs I am using,I had to open one of the 3"
cases...That hurt! Oscar
