I am thinking of having another BPCR rifle built. Im leaning towards a C Sharps high wall in 40-65 with a 30"barrel. Ive been looking at various barrel makers as Im also considering having the barrel I want put on it. I have looked at kriegers site ( as an old High power shooter these were my go to for barrels for the service rifles), Lilja, shilen, douglas, hart, Bartlien, brux, pac-nor, and a few others. Its interesting and also baffling to a point. Krieger offers standard cut rifling hand lapped blanks in standard form, 5R form, and henry style. Shilen has standard and Rachet style rifling listed. several offer gain twist. Diffrent numbers of lands/grooves between the diffrent makers also. Diffrent tupes of manufacturing processes also, cut rifled hand lapped, broached some hand lapped others didnt say, button rifled, some cyrogenically treat to stress relieve blanks before and after manufacter, some stock before some dont say. I am planning on Chrome moly blank as I just cant see a high wall or other action with stainless barrel on it looking right. Im interested in opinions on what rifling form and makers are recomended? What experiences with them? I have a Green mountain on my hepburn and douglas on the cpa. I am leaning towards a round straight taper countor to make the weight limit and end up around 11 Lbs. Is the henry rifling worth the added cost? would 5R form work with BP and cast bullets ( it was a big plus in high power service rifle). Would the deeper rifling and better finish of the cut rifled be a plus? Alot of questions raised by my searches
