Saw mention of the rare Ruger trapgun having a straight rifled barrel to prevent wad rotation. Hastings, of course, makes such barrels too.<br>
<br>
Do wads really rotate in barrels enough to cause degraded patterns?<br>
<br>
If so, is this a cost effective solution? Do the results justify the expense<br>
<br>
Are there other solutions?<br>
<br>
What, exactly, causes wad rotation? Is it a function of the wad? Or is it a function of the barrel? If the barrel is perfectly round and mirror polished, there should be nothing to impart a spin on the wad. I can see how honing marks could cause it, but that would not be a mirror polish. Further, I've seen slugs strip right through a rifled choke tube and not turn. It's hard to believe imperfections not visible to the naked eye would have any influence on a wad.
