Just picked up my new Winchester 1885 38-55. Slugged and got .368 bore and .376 for groove, same as published specs. The twist is 1-15. I have two standard 250 grain molds, one Lyman and one Rapine. They are straight sided and very difficult to breech seat, even at 1-32 mix. I need a tapered bullet to breech seat with smokeless. Years ago Jerry Barnett produced one for my original Ballard #8 38-55, a true .38. I believe Jerry is no longer in business. Who in the world of custom makers would you recommend for this custom job?
