Some of the CBAs best shooters use wads behind the cast bullet. I haven't had any luck in getting better accuracy by using wads.
What do we know about wads? What do they do to improve a smokeless powder cast bullet load? Do they act as a seal behind the bullet in case the fit of bullet to throat doesn't quite do it? Do they help wipe the bore so there is a uniform condition for the next shot? When Merrill Martin was experimenting with cast bullets and writing for the now defunct Precision Shooting magazine he had good luck with them with plain-based bullets in fixed ammunition. He claimed they helped seal and also protected the soft base of the bullet from being damaged from high speed powder grains. He had a lot of photos to show how they prevented both kinds of damage. If I remember correctly he used sixty mil high-density polyethylene most of the time. Others have used fiber wads of various sorts and claimed success. Can wads improve our cast bullet loads? What is the best material and what size? Or are they just one of those things some of us do because we think it is logical and we could stop doing it and shoot just as well? John
