Re-slugged the bore and also did a cast 3/4 of an inch down the barrel, .316.
My chamber casting measurements are: Base .424. Neck is .3495. Length is the only thing I could not nail, but I came up with 1.820 and that may be a little on the long side. It is looking like the 8.15x46R round. I am still going to a gunsmith. If he give the OK, I will start acquiring dies, and bullets as I have some spent 30-30 cases. If not, it will be a wall hanger with a story.
Thanks to all.
