Hello Krink 545,
I have built my own whisper based on a Brno Fox rifle.
I have bought my own reamer from pacific tool and gage.
A barrel with 1 in 8" twist from Border barrel in Scotland.
I used the workshop of a friend of mine which is well equiped.
And I loved building it, and it was maybe a bit cheaper than if I had it done buy a professional gunsmith arround here in Europe.
But, if you live in The US, I think it is fare easier and cheaper to get an action rebarreled by a company like Pac-Nor, shilen, ssk...
But I can understand the pleasure you get from building your own toys.
Up to you.
I think you can rent a reamer from
www.reamerentals.com ifyou do not want to buy one.
Good luke.
