Brit,
3 drams and an ounce and a quarter to ounce and a half will get the job done.
If you get a chance, read GT Garwoods books. you will find in there the loads that the East Coast market gunners were using in their 10 and 8 bores. Much lighter than some would think, And they were doing it for a living.
Brit,
Our posts crossed.
Where to start?
Ok, pressure. More pressure can be developed in a longer barrel Without (capital W) blowing the pattern, because as the charge goes up the spout, pressure drops. (simplified version)
In a shorter barrel, pressure can be kept down somewhat by using a larger grain of powder.
Yes, 3 F Will work, but I can just about guarantee the Patterns will not be as good as if you use 2 or 1F powder.
