Ever since reading Forsyth's little book, I've wanted a SxS 14 bore rifle. Friend of mine had 2 tapered round bls. made but I could not afford, at that time,
to purchase them from him. I do not think he ever built the DR with them - what a hunting rifle THAT would be.
The Kodiaks usually don't even shoot remotely together- especially with the slugs everyone seems to want to shoot in them.
They did or maybe still do make a .54 and perhaps a .50. This is likely the cheapest way of obtaining one, but how it shoots might be a $#@* shoot at best.
I lucked out with my .58 Kodiak.
100gr. 2F put the barrels together at 50 meters. 110gr. made then shoot parallel.
80 and 90gr. made them cross and shoot to different elevations.
120gr. made them cross again and reverse the elevation of impacts.
The bottom picture shows the hammer/nipple/fence relationship. Some are even worse than this.
The picture second up from the bottom shows the same 'shot' as modified by me to make the fences operational.
This is a 7 shot group at 50 yards with 100gr. 2F GOEX
After finding the 100gr. and 110gr. loads, I removed their EXTRA rear sight that you are supposed to sight in
for the 'bad' barrel.
