I've often wondered if bedding an airgun would have any effect on accuracy. Obviously powder burners benefit from it because movement between the action and the stock is effectively eliminated, but would bedding an airgun have the same effect? I can't see it doing anything for a PCP, but springers can have harsh firing cycles and vibrations that might benefit from a glass bedding job.

Any thoughts? Has anyone ever done this before?

I've been wondering about this as well and I'm looking forward to the responses. In theory bedding an airgun and free floating the barrel should have a similar affect as it does on powder burners...at least, I think it should. If using the "artillery hold" on airguns improves accuracy by letting the gun recoil freely, shouldn't letting the barrel do it's own thing further improve accuracy?

Maybe somebody more scientific and adventurous than myself will do a little experiment so we can get a definitive answer to this. Fingers crossed! :D

Those are my thoughts exactly!
I have been a PB gunsmith since 1990 and always bedded the action and the first inch or so of the barrel!

I bedded my QB57 in a stock I made using body filler and applying it in small sections because it would set up so fast.
I wrapped the tube with tape and or saran wrap, I used long setscrews for alignment with the existing hole locations.
If I screwed up I could dig it out and try again, which I only had to do once. It turned out well and with the snug fit it felt more solid. I will do it again on my next stock for sure.

It can have a serious effect on pneumatics to springers, constantly chasing zero.

Aluminium and wood moves so only want the action bedded in the right place, no need for P38 etc. Action direct on to the stock more than good enough.
Worst thing you will do is cylinder and barrel touching the stock. Barrel needs relief ie clearance so does the cylinder in its entirety.

Very poor inlet jobs have created zero shift as well, whilst others have got round it by leaving action very loose so that it rattles about.

Work this one out, aluminium stock with free floating action on one central stock fixing not standard. Slacken cylinder 1/32 of a rev and see zero shift, keep on rotating 1/32 intervals and see zero move left to right. All told at only 20 yards saw 3/8" drop and 1/4" left, then going right there after.

If you google Hw50 mods + bedding , you will get a s.african airgun site with some good real-world info [not speculation] on it.
