Just picked up a Kodiak .58 double rifle for testing. When the weather warms up a bit, I'll give it a go at the range. The owner says he returned it to Pedersoli, complaining about the crappy regulation. The gun they returned, this one I now have, supposedly regulates parallel at 50 and 100 yards using 3 drams of 2F powder and a round ball - we'll see. I usually prefer much heavier charges for hunting with a .58, and especially with this guns excessive weight of 10 1/2 pounds. 9 to 9 1/2 lbs. would have been preferred.

The first thing I did to the gun was to re-crown the muzzles. I thin pulled the nipples to see how many threads there were between the top surface and top of the flash channel to see if I could mill the nipple seats down 1/16" to get a better curl of the hammer's nose over the fence. there appears to be enough - maybe 7 threads.

The nipples that came with the gun have very long noses, which could also be trimmed a bit as they have very straight shanks which will still allow the caps to fit properly. This will also allow the hammers to curl over farther. I did note the nipple's threads aren't very snug in the breech threads, so might fore-go milling the nipple seats - we'll see.

The owner reports 3" groups at 100 yards, firing alternately, rights and lefts. That would be nice. Dang weather - too cold and windy for range shooting at 15 degrees now and supposed to drop to 2 or 3 this afternoon - (-16C).

Hope it warms up by the weekend.

Martin - have you done any more testing?
