Hey guys I've been working on my goose barrel bore dimensions . I've been step drilling to different depths but would like to smooth things out on the inside to get a little more speed out of the call I've looked at remmers but I don't know if that would make a good smooth finish on acrylic calls and looked into a tapered drill bit an that seamed the best solution but a custom bit is quite expensive and seems like no tool an die company wanted to make just one custom bit they wanted ya to order multiple any info is appreciated . what's everyone using thanks
