Thanks for the answers I just want to lern as much as posible about double rifles.
My rifle is a (humble) Pedersoli Kodiak 58”.
My charge: REAL 445grs and 100 grs of FFFg (the only powder I can get)
I try to find a regulating charge many times but, as I find a promising charge, finished my powder supply.
I get funny groups when shooting from a rest so I will shoot from standing position without rest. Even with only elbows on the bench, I have two separate groups, I think I change the way I use the rest.
The same charge, using new powder, cross fire at 50 meters.
This new powder is “lighter”(same volume but less weight), so I have to find a new regulating charge.
If time do not affect point of impact (regulation), it would be much easier to shot each barrel separately with time to aim. Am I wrong?
Please let me know if I do not understand your explanations.
Thanks
Martin
