Pedersoli Kodiak .58 Regulation
      #325862 - 15/03/19 04:54 AM

Some time back, I traded into a Kodiak .58 SxS Pedersoli rifle. These come with 2 adjustable sights, mounted on the rib in the middle of the barrel. Since the leaf folds down, you are supposed to sight each leaf in for one of the barrels, raising and lowering the leafs as needed.
As received, the hammers did not curl over the fences, actually sitting proud on to of very high nipples, allowing cap fragments to fly all over - no protection.
here is the 'action' as received.



I did not like the relationship of the nipples, nor the bright steel of the locks, tank and trigger guard, nor the horrid cheek piece, so I changed those items and refinished the stock. I also filed the rear sight to a V shape. so








I started off using 3 drams(82gr.) of 2F GOEX powder with a .562" ball and .021" ticking patch.
The barrels printed right barrel 2" over the left, and 2" crossing using just one of the rear sights. I increased the charge to 90gr. and the barrels came closer together, using the same combination of components. I increased the powder further and the barrels then shot one above the other about a couple inches apart at 50meters+. This is displayed on the left target. The right target shows an offhand shot, one from each barrel holding accordingly, right barrel low and left barrel right on, still using just one sight. by this time, I had removed the front, rear sight from the rib.



After this test, I changed to a denim patch of .022" thickness - note the change in grouping!



I increased the charge further to 110gr. and found the barrels shooting almost exactly parallel with that load and the .562" ball. I changed to a Lyman mould casting a .574" ball and grouping remained the same- parallel with 110gr. and into the same group with the .574" and 100gr. 2F. As grouping at 100 meters was the same from the 100gr. load and the 110gr. load, I stayed with the 100gr. 2F charge. At this point, I used this rifle for trail walks at our club and relished in shooting rights and lefts on the gong targets- clang/clang. Oft times I'd run the whole course with narry a miss. I then became bored with this rifle and sold it to a lawyer in town. I'd actually like it back now. Hmmm.

Interesting, I have seen your posts before about this rifle. My son has one in .58 . He has taken several white tail deer with it, I don't remember his load but he uses a .575 ball. Did you just deepen the hammer cups? Do you remember what the twist was? The new ones are being made for SLUGS!!! The .50 and .54 have a 24 inch twist and the .58 has a 48 inch twist, They are for the hunters that think you need HUGE slugs to kill game!!!! LOL!!

Mine is a 72cal and I have yet to get it to regulate.

Hi Ed. The twist in mine was 56", seems to me and about .008" rifling depth. Dang- might have been 48", though. Na - 56", an older rifle from the 1980's.
I deepened the cups as well as shortened the nipples. Must watch, that the main spring doesn't crack the wood out below the locks, so there are limits as to how much lowering (= more spring travel) is done.
I would be very edgy about shooting slugs in a SxS - concerning the movement of the other barrels slug on recoil, creating a space between powder and slug.
Too, of course, just not needed.
As noted, I started off with a LEE DC mould and then switched to the Lyman .570" Which actually cast .574" X .574".

What surprised me about the shiny locks and trigger guard, is they took cold blue and turned very dark for me, as you can see in the bottom picture.

Oh yeah- forgot to mention. There was a 1 pound bar of lead inside the butt. It started rattling as I was sanding the stock, prior to refinishing it. The vibration of the orbital sander, loosened the lead so I was easily able to remove it.
I much -refer slightly heavy barrels and the 1pound lighter gun. It was already almost 9 1/2 pounds without the lead, just about perfect for a hunting rifle, imho. That is what my .69 weighs.

Wayne, sometimes they can be really difficult. A friend of mine who had one, a .58 like mine, shot only slugs in it and the closest he got them, was about 10" at 50 yards. Useless, as far as I could tell.

Sounds like mine. With minies. Haven't tried anything else ever in it. Want to try round balls in it one day.

Good thread for future research.

We could do that next Spring, John. We're planing on a month, 4 weeks.
Thought South first, then heading up North as it cools.
