After much trial and error I finally found my rifle's regulation point. It's a 1980's vintage Pedersoli Kodiak double rifle in .50 cal. The new ones are 1:24 and are basically heavy slug rifles. This one, I discovered, is a 1:48. But I could find no info on what it likes to shoot. That twist can cover various bullets and slugs. I had to laboriously track various projectiles and charges between 25 and 75 yards. Stuff that worked OK at 50 went haywire at 75 more than I would have expected. For example PRB's with 110 grains FFG were great at 50 but way high and frayed at 75 and off paper at 100. Slugs that were OK at 25 were off beyond that.
Anyway I finally discovered the beast really really likes old school PRB's with 90 grains FFG and no more. With that load I got solid regulation at 75 yards:
Here's the big boy in action with the extra big Great Plains slugs. The right barrel is actually OK with these but lefty goes WAY left after 25 yards.

As you can see recoil is minimal even with a max charge and huge slugs. The weight of the rifle makes a big difference. Sure is fun to shoot! It always makes a splash at the range.
