Hi .303 guy, I suppose there`s a lot of ways of doing this , like a sine ways rifling bar, just have to look on the internet for ideas. I just got lucky with my gearbox and bike bits , and the end result is allways different to what you think, I was going for a twist of 1-18" and through I had it, but no it came out 1-20" so it will have to do. Now the barrel is cut octagonal and stopped short at the breech end so I could grind the tulip bit that the Sharps barrel has at the breech end . Now all I`v got to do is polish and clean her up and at this stage will get it heat treated , but after xmas, I`m having a holiday, cheers, Homebrew.357.![]()
, Octagonal done.
, A raw Sharps Octagonal barrel, hope it shots strait.
, Grinding the tulip .
, Bit of a polish should help.
