I am totally in agreement with you on the twist rates Chet. I suppose it just depends on the bullet you are shooting though. If you are going to shoot something like 200 grain .400 bullets in lead, you might not have the best results with a fast twist. I can't say for sure though, because I haven't tried that bullet in my fast twist Whites.
You have a .410 super don't you? Is that a 1 in 14 twist? What have you been shooting out of that?
