Hatton Shotgun Breaching Round

Would someone know the origin of the name “Hatton”? Is it the name of the inventor, original maker (British?) or what? Many thanks!



I think “Hatton” is a term originating from the UK for these types of shells, which is just another name for them like “Avon” rds, “Shok-Lock” rds, or lockbusters. The earliest one I have seen was from the 70’s or early 80’s, had a maroon casing, and a white cardboard plug on the end which said “shok-lock”, and I believe it was by AAI.

Quite so, but while the origin of “Avon” is easily explained (after the door-knocking salesmen of the Avon company), the origin of “Hatton” is obscure.



The Hatton rds are/were sold by Clucas MoE. I remember the rds being trialed sometime between 1983 and 1987. I think they were named after the bloke who thought them up, but my memory may well be wrong. Tony Williams will probably know.

At one point we cut the barrel of some Remington 870’s down level with the mag tube and put pistol grips on them. The “user” said that firing Hatton rds to blow in a door through these modified 870’s was “sporty”. These were 870’s were nicknamed as Access or Barclay Cards for a while.

Can someone please tell me the difference between a door breaching round and a standard solid slug.

With reference to the Hatton round the ‘slug’ is made of compressed lead powder which breaks up very quickly after hitting the target, less chance of a ricochet etc etc

Exactly; with a “slug” you generally want as much penetration as possible, but a “breaching” round is simply meant to blow locks or hinges off of a door frame (allowing quick entry) without causing damage to whomever/whatever is on the other side of that door. However, if you were to actually SHOOT someone with a breaching round, it would do just as much damage as a regular slug.

So would it be fair to call it a frangible projectile?

I think that although it behaves like a frangible bullet after hitting the target, I wouldn’t call it a frangible round but thats only my own opinion.
