You're all being very cheapo'ophobic about Gats (the proper TJ Harrington versions).
I was utterly awesome with mine, and I'm pretty sure if I'd also had a Gat rifle as a kid, I'd have been equally great with it.
So there.
I have an Edgar Brothers 60 whose barrel is worn smooth, presumably with steel BBs.
Can't hit a barn door with it, gave up trying to zero it as I couldn't even figure out where the pellets were going.
Well my .25 Rapid FAC is hopelessly inaccurate with any pellet other than JSB exact/AA field which are ragged single hole.
By which I mean at 42yds zero only about 8-9/12 will hit a sheet of A4 paper (Norica Apache only 7/12)
The gat pistol? Really!
I remember shooting apples, oranges, tins and lots of other things at 5 yards I had lots of fun, it started my enjoyment of air guns!
I'd vote for the ro72, I got it given. Every time I shot it, it hurt my trigger finger....a lot!! It creaked, vibrated, and hurt to shoot. Accuracy = none. Terrible, maybe I had a bad one....but
I would say the Gat - But it was find at the ranges it was designed for.
Worst is possibly the dodgy Baikals used at fairground gallerys which fires with a horrendous twang and take a minute to stop vibrating.
As for unintentionally bad... my much loved HW35, which a friend borrowed for rabbiting, and returned with a bent barrel claiming it couldn't hit anything. Found the bent barrel when i tried to zero it in the back garden and made a hole in my shed 2 meters over the target at about 10 meter range.
With friends like that, who needs enemas?
Kral Puncher Breaker, as accurate as Diane Abbots adding up.....
Got to be the Gat...
Gun power stealth , one of the first ones . Really shocking , shotgun patterns .
