This mat isn't
just sold as target nappies, it comes in lengths of up to 20m (in single thickness)
So it
can be used as a "target nappy" behind a boss as described by TT, but it can also be used as an alternative to a net for indoor shooting etc.
It looks like a thick heavy duty felt, and I'd not seen it until this winter, it's also quite bulky which is one reason our club still replaced our tatty old net with a new net and not some of this, but I was quite impressed with its arrow stopping abilities. It's not arrow-proof but it seems much better than any netting I've encountered.
I came across it on a Merlin visit where one of the staff demonstrated it by hanging one of the (double thickness) target nappies and shooting it with a compound from 2 or 3 meters - the arrow bounced off!
With our club indoor netting if I push one of my carbon ones or ACGs against the mesh I can force it between strands of the net without much effort (and the odd arrow pinched off the rest has gone straight through in the past), but I cant get the same arrow to penetrate the (single thickness) mat by hand.
We've got a piece of the mat at home for training, and test shooting carbon ones with 42# otf, the arrows penetrated the mat but stopped mid-shaft, before reaching the fletchings. The mat sort of stretches where it's been hit hard (and stays stretched), and I doubt it would handle repeated shots in the same place as well as the first, but I remain quite impressed.
It's not had to stop anything for real, the boss has been doing that
, but I'm pretty confident that it would if required.
If I shot the same arrows at a normal net, the first thing I'd expect to slow the arrow would be the wall behind!
2114 X7s from my bow just bounce off, but I'd give a normal net a reasonable chance of stopping those anyway because of the diameter.
My wife shoots compound with about 35# peak, and the mat also stopped her ACCs mid shaft. I'm sure a more powerful compound or some of the very conical points would be a very different story though.
