Redesign a "Bell Target" for 25y/.22RF?

So if a guy wanted to redesign an English air-rifle "Bell Target" (designed for 6-7 yards, indoors, air rifle) for .25 yards, outdoors, for .22 rimfire....

I've got no problem "scaling" things up, or building the "center hit bell clapper" or whatever you want to call the mechanism that does the dinging when you hit the "5" ring.. Nice piece of AR500 plate, etc etc...

My concern is SAFETY... a flat (90 degree) plate, with a hole in it, does not strike me (please excuse the unintended pun there) as a good design for .22 rimfire at 25 yards.

So what ideas do YOU have to alter the design to make an effective, and SAFE, "bell target" with suitable "bullet trapping"?

I've got a couple ideas... but I would love to hear what anyone ELSE has for ideas!

To perhaps start a thought process, here is an idea that occurred to me while practicing offhand yesterday. I use a similar trap for my air rifle which gave me the idea that you might use two of them (front to back as shown) to accommodate your safety issues. With such a setup, I don't think you would get any bullet fragment bounce-back from misses (front trap) or those making it through to the bell ringer (back trap).
As far as the bell ringing mechanism, that's above my pay-grade.
The bullet traps cost about $40.

I built 5 air rifle bell targets for a club I belonged to. Even with air rifles, velocity needs to be very limited. Even so, pellets will occasionally return to the shooter and friends. Eye protection for everyone is a must.

You could easily beef things up for .22rf, but velocity would certainly still need limits. Part of bell targets is the dead vertical steel circle that forms the target. If you put things through the bullseye bell hole every time, no issue, but if every round goes there for every shooter, where's the fun/challenge? I don't think I'd want to shoot even standard velocity LR rounds. Keep things safe.

What about a completely ROUND bell set deep within a trap? The curvature should deflect off all hits, less one dead on from the front.

Also consider limiting ammo to Aquila Colibri, which only uses the priming compound for power.

All of my single shots shoot one tiny ragged hole with cast bullets ... it's just the following shots that tend to open up my groups Wink ...

Thanks for the replies!

The "bell" itself is easy.. behind the "hole" there's a swinger (with enough "swing" to soak up the kinetic energy of a hit), connected to an arm that strikes the bell.   

It's the face-plate that is precisely my safety concern...
I will definitely have the whole face-plate-and-bell-mechanism mounted inside a trap-box of some kind with sloped steel walls (to direct any "misses" into the box).   
I'm wondering if mounting the whole face-plate-and-bell-mechanism on a "swinger" arm would "soak up" enough kinetic energy (in addition to having it angled down 10-15 degrees) to keep rounds where they belong?

My ideal is for this to be used with any .22 Short, Long, and Long Rifle (up to and including high velocity) so it could be used by a wider variety of folks at our range... not just shooters who can spell "Colibri".  Smiley

I wish I could find a better picture of the mechanism of the Bell Targets... they're really fairly simple, and very cool.

We have a indoor range here and they hung heavy rubber in front of the back stop to prevent splash back, it works very well.
Before they did that, you'd find whole or large chuncks of bullet 10 to as far as 20 feet in front of the back stop.
