machined to fit.. 24 inch or so in length and fireing #3 Hornady swaged buckshot ..with a fully modded valve and ported and bulked .
Interesting to see the results of that ..it would make terrific varminter .

Frank, can you do the machining yourself or do you know of a machine shop that will do this for you? There would be a fair amount of delicate machining to make the barrel fit, no?

I would have to order the barrel ..that may take a while to get here ,
then have a machinist take the measurements from the qb barrel and replicate them on the HW barrel .The external Diameter for the HW barrel
is fine ..you can get a 14mm HW barrel in .25 . Its the fitting into the breech that he will do . and the grooves for the o rings , you can use the same bolt ..remove the probe ..and use a drill bit for a probe , cut down to size ..and so it will seal on the .25 barrel you can sleeve it with polyethylene ..i think this is very doable .
