Bolt action Hatsans not so good.

My 25 hydra was reliable all day long. It was ugly like every hatsan, but rock solid reliable. Sold it because the whole idea of the quick change caliber design was a joke. If I switched from 25 to 177, my velocity was in the 1100 fps range with 10 grain and fell off like a rock. Had to be tuned with the change each time.
