I have two rifles of the same period with period aperture sights. Why not see how the two compare. The BSA Light is .177 but the Haenel Model 3 is in .22. Used Hobbys for both. My lazy backyard style with elbow on a table. The Haenel had a advantage with a very light trigger, I’m sure someone probably worked on it cause I read they were usually not that great? Bottom line I think I’ll keep both rifles! Lol
