Like a lot of other projects I've done, this is the result of me having a stupid idea and nobody telling me that it's stupid!
I know that I'm well into the range of diminishing returns with this one. I'd be happy to get 2850 fps from a 300gr bullet out of the 20" barrel. More is always better though!
All the parts are finally here! It's heading of to the smith tomorrow.
I had some problems with the smith who made my reloading dies which set me back 5 months. I'm hoping that I can have it done in time for hunting season this fall though.
