Anyone know a source for Source for Kynoch foam wads?
I just use backer rod from the local big box hardware store. It's much cheaper and does the same thing. For your's 1/2" dia. should be fine Cut it off so it's slightly longer than the gap between the powder column and where the bullet will be seated.
I also us a bunch of Dacron filler in my loads.
KynochUSA.com will have their foam.
I've had excellent experience with backer rod as well.
I think Trader Keith carries Kynamco Foam wads:
