Cotton Cordell ?
 

Does it matter any if you load the bigger popper from the rear top or rear bottom or is it all the same & how much shot, an ounce I assume is OK.

Can add an ounce I am assuming your talking pencil here.... Load it from top bottom and seal it up with some epoxy after you melt it back...

Makai,
Try and contact Stiff Tip. He uses different loads for different applications. Has a special weight/load for the canal and a lighter load for general surf use.

It was mentioned that the bomber version and possibly the original cordell have chambers that have a gap of 1/8 inch between chambers.
Therefore using a lead shot of greater then 01 will prevent the shot from moving between chambers

My friend uses 7 shot, and he says that one load is 1-1/8 oz. Just cuts the shell and dumps the shot into the plug.

Of course in Mass you need an FID card, at minimum, to buy ammo.

Purchase only the lead shot by the pound.
