Looking at fitting a barrel blank to a .38 spl - K frame that is lacking a barrel, Since this is a blank I plan to try several different ideas (milled integral front sight , 5" barrel heavy profile, about like the original heavy 10 but perhaps a touch heavier)
This barrel will only see cast bullets, mostly 158gr SWC's and 148 tin cans etc....In loadings from very mild to +P
The cylinder gap I'm aiming to get around .003"
Where I am hanging up at is how to go about doing the forcing cone from a blank.....how far in and what degree I should go. I'm not sure if I'll make my own forcing cone reamer at this time or not ( I have heat treat capabilities)
Also on the issue of how to handle the ejection rod lockup. it is the snub nose type ejection rod
I can do multiple barrels from the blank I have so if I mess it up it can always be adjusted or just tossed or whatever. But I don't want to waste my material, I've done rifle barrels just never something with this many nuances and need for detail.
