I have an AA510 .22 in carbine. Love it. No HW100 to compare it to. Also have a Daystate Regal and i think the AA has a slight edge over that in terms of quality although it is also a very fine gun. I get ~30 shot with 18.13 gr before falling off reg on the AA. Also am a fan of the side lever vs bolt.
I would go with the AA 510, just being as I have had a few and they are great guns.Now that isn't saying that the HW100 is a bad gun. Either one you will like.Get the one that uses the magazine that you like, as well as the stock you like.
I have the S510 in .177 and it is a definite keeper. I also had a Daystate Regal Huntsman in .25 sold the huntsman and will keep my S510 until somebody else has to decide what to do with all my rifles.
I have 2 HW100's one is the HW100 T FSB shrouded barrel and the other is the HW100BP bullpup with Moderator, both are absolutely awesome guns, laser accurate and very dependable, also very quiet, I would never sell these guns, keepers for life, I don't have any AA guns, but I hear the 510 XS ultimate sporter is an excellent gun.
HW100 has a Limited Lifetime warranty, as long as you do not take the gun apart, you must have it serviced at a Weihrauch athorized service center, like AoA.
I've had both. I now have two HW100s and no S510. The HW100 is better in almost every way.Trigger is much better.It's regulated. The magazine is foolproof and can't double load. The HW100 is not better in these three ways: More prone to leak, they simply have more seals. The barrels sometimes are picky in .22It's heavier. At full FAC power shot count is pretty lame on both. Don't know your power restrictions if there are any. One major issue I had with my S500, that in my opinion ruined an otherwise brilliant gun: The POI shifted throughout the shot string, and anytime the stock screw torque changed or the action was bumped in the stock. The action is held in with a single screw, and the stock is inlet tight to the airtube, which is tied to the barrel with a barrel band. Terrible design and caused me untold amounts of grief. Just my findings.
I don't own either, but looked at them a few years back when my brother wanted to buy a PCP. What I remember (and should be verified about current models) is: That the HW100's magazine was much simpler to load than most PCPs. At that time, the HW100 was regulated, but the hammer spring tension was not simply externally adjustable. This may have changed. HW100 used to have models with "conventional" stocks and fully shrouded barrel. Now, the fewer conventional stock models have a obvious silencer on the end of a slim barrel. I don't like the look. The Canadian version probably just has a slim barrel.The AA510 are very nicely made. I liked the fact that they have a Lothar Walther barrel. Mags are slower to load than the HW100. Pressure regulation was not standard then - it is now. This air rifle has some external power adjustability. I like that the S510 is availed as a carbine with conventional looking stock and shrouded barrel. I don't know if the Canadian barrel has a shroud, or if the shroud is blind and non-functional.User manuals:https://www.weihrauch-sport.de/wp-content/uploads/2021/03/HW-100-FSB-dtsch.-engl.pdfhttps://drive.google.com/file/d/1b0efvV2sIC52bgX0HinhcZ_hpAifxog8/viewFrom: https://www.air-arms.co.uk/downloads.html

I too am not a fan of thin barrels. The S510 is shrouded (but no baffling here - suppression, even on an airgun is illegal here). The HW100 I am considering has a walnut stock with thumbhole and the S510 has a more traditional stock. Both beautiful rifles so hard decision. I am looking for something that is also very accurate out to 50 m and beyond.
