Had one in 25 and that got costly quick. Also, only 20 shots on a full for 25 if you actually wanted power out of it. 38 fpe was about it for 20 shots.
Now my 25 hydra was about 42 fpe for 20 shots. Weird because they basically have the same valve/hammer/tube/barrels. The hydra has another adjustment screw under the action that smoothed out the shot string along with hammer spring tinkering.
