Yes, yes - very light. The small ball might work OK with thick patch and light loads, indeed.

I would think something like 60gr. to 75gr. 2F. Quite likely will shoot better, the more powder you put in it.

Even 75gr. 2F is not a very fast load, but should work for smaller game just fine.

Plans for the spring are finalizing, should be able to let you know some dates soon.
