"the glue can be flower paste, diluted casine (Elmer's) or even a rub-on glue stick."
Stumpy....Being very new to this, my experiments have been somewhat limited, but I have found, beyond a doubt, that a thin flour / water paste mix, works best for the "Shot-Capsules" that I have had some success with. The paper seems to make a great OP wad when loaded as suggested, and a shot card seems to keep the shot from falling out. I feel sure I'm busting the paper capsule seal when I seat the load....I "think" this may be desireable.
Help me out here....will the forward movement, from a load at rest, be great enough to tear the paper loose from the shot capsule and permit spreading? Or, do I need to insure that capsule is broke before I seat the OS card?
I guess the real question, for me is...can you ever control this?
I have had a few loads, when using Elmers glue, that paterned at about 14" / 16" and were somewhat oblong, at twenty five yards....good news? bad news? I don't know. I do know I can't shoot well enough to use that kind of pattern.
I "think" someone proficient with this may be able to control the pattern by using different glue, or paper, or something.
I also realize you are talking about roundball here, and I don't want to take away from that, maybe you can kinda slide this in under "other"???
