Right, I had 7rds of ammo I did not want to shoot at deer again, bullet to tough so in the interest of this thread I went target shooting.
Now, there are some caveats!
I hate shooting at paper, never have liked it.
My eyes are knackered, especially my right eye I shoot with and last of all I hate shooting at paper!
Now if you want to skip the two targets and jump to the 150 paces target make sure you are sitting! My legs nearly went from under me when I saw it! It's the best group I've ever shot on open sights! Oh and 150 good paces, not Zimmer frame steps!
First off I shot a small game load of 8.5gn of Herco and a Speer 100 gn plinker.
Shot a single round at 20, 30, 40&50 paces.
Just aiming for centre.

Next is the 100 paces and it went tits up.
I got two together and then dropped one

.
The hole by the hammer was a 150 paces shot. It's a poor target and it was partly obscured by the crop. That's my excuse anyway.
So with little confidence I put the next card up where I could see the dam thing and went back 150.
Loaded the last three rounds and did my level best.
Wow, I knew they felt good but wow

.

So can leverguns shoot on opens? Yes, yes they can. Even for the visually impaired!

Sorry I just edited the last photo, I'd put the wrong one up.
