building a replacement barrel

(1/3) > >>

burch:
O.K. here`s my new idea. I have a 50 cal. GPR and would like to build a drop in smooth bore barrel for it OR have one built if that`s my option. So how hard is it to do this and what all is involved.  I`ve never done anything like this before but have done a lot of my own gunsmithing.

             Burch  

Captchee:
well first of it would have to be octagon at least to the  end cap . From there she could go round   and an under rib plac4ed on it  to lower the rr thimbles .

 The only issue would be caliber you were looking at ?.
 You could even use a standard rifle barrel   for the gun and just  ream it out

burch:
So just say for instance I had another 50cal. barrel and had it reamed out. What ga. would I be looking at and what ball dia. ?

melsdad:
I THINK IF .015 / .020 WERE REAMED OUT OF THE BORE YOU WOULD END UP AROUND A 33 GUAGE.

.550 would be a 28 guage

I am querious myself to hear other responses

Captchee:
should be able to get a 28 gage out of it  IE bore it out to .540 + or minus
