Recoiless vs recoiling FWB experiment

[ptdunk]

Anyone remember the 80s ads (Sussex Armoury, I think) for discounted HW55s claiming scientific proof that the pellet had left the barrel before any recoil-induced movement took place?

I always thought they were BS.

I think that idea may have come from the manufacturer, a 1968 catalogue says the same thing (top right in text):

Also says same about FWB110,they call it 'delayed recoil', feature no. '4'



I think they recon the pellet is out of the barrel before the piston gets to end of travel, maybe possible if there was enough swept air volume? although you'd still get the initial rearward movement as the spring expands.

Don't know how you'd measure it, other than with a super high speed camera.

This from 1978 shows a few Webley Osprey Supertargets in the mix, one got silver.

as Geezer said it would be interesting to see some 1960's result lists.

Thanks for that. Kudos to Mr Taylor getting so high up with an Osprey.

Also note the 1968 comment about scores improving over the previous five years - exactly when the recoilless rifles started making their mark. Not, I think, a total coincidence.

"A by-product of this delayed recoil sequence is almost total silence on firing a result of the air-flow principle."

Sounds like dishonest cobblers to me! Or maybe they believed this twaddle (surely it was actually nonsense?).

Definitely a load of flannel….

To be fair ‘Air rifle headquarters’ was an American catalogue written by Ian Law, I think he was trying to convince Americans of the advantage of airguns over firearms, in comparison they probably were a bit quieter. Nothing to do with the ‘delayed recoil’ though…He mentions the ‘virtual silence’ of airguns a lot actually, as well as the accuracy and also the revelation that they don’t produce any smoke!

You might find these scans, which tell the story when ARH went belly up in the early '80s (apparently their finances weren't helped by the generous terms they offered customers), interesting Matt:

Thanks Danny,
seems like ARH got the U.S airgun ball rolling, and Beeman ran with it? ... fair enough.
Beemans 1982 'Safari' to all the German airgun Factories sounds like my dream Holiday.

Will try and have a wander round Zella Mehlis one day...

That’s about right, though it was (your earlier post) Robert Law, not Ian Law, who was, IIRC, a British FT shooter.
