Barrel twist rate

I would appreciate it very much if you can tell me what the twist rate is for my AA S510 .177, .22, and .25 rifles. Thanks

As far as I can find they are standard Lothar Walther twist rate at 1:17.7”.
Can’t find any reference to anything other they are standard LW and all the caliber should mention all being the same.

My understanding too... (= 1 in 450mm). Had heard also the figure 1:18 but I'm guessing that was just rounded to the nearest inch.

I'm sure AA would confirm if you phoned and asked for technical advice.
