I have the same brush gun I bought several years ago here on the 'fire. It had a barrel obstruction and was shortened to I believe 17 1/4" The 35 Winchester can do what you ask and if the stock is shortened to the shortest LOP you can utilize you will have a great gun for the treed bear. Use a cast WFN sort of a 250 gr or more. Lots of energy transfer will happen. Be Well, Rustyzipper.

Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy. Its inherent virtue is the equal sharing of misery. Winston Churchill.
