The cost of a barrel is cheap vs a whole gun. A fifty has really good potential as a big dangerous game backup and for that id want a few more shots but id bet u could run that encore at a higher velocity outta that 12" barrel. Double tap lists loads out of a smith for 400gr at over 1800 fps. I bet u should be able to run over 2000 outta that barrel?!?! Id love to see what u could do
