RE: Tried Blackhorn with mixed results..
My daughter’s Kodiak .45 shoots BH209 good after I drilled out the breech plug 1/8" one end and .035" muzzle end. I found Win primers have never gave me a hangfire. I have tried Fed 209a and CCI209M. keep plug clean. Gun shoots 200 SW 90 bh209 1950fps 1-1.5"MOA.
