What exactly is cream-o-wheat? Is it the germ,or some other part of the grain?......Ive only used wheat bran,which is part of the husk.It was suggested by a Kiwi on this forum,works ok,and is very cheap,.....but all veg. fillers seem to pick up moisture,and so may degrade powder if loaded rounds are stored .Ive not tried dacron,but I have savaged some dacron from an old pillow........and when I find some foam rod Ill try that.
