Well, yes and know....with a conical I can see two different problems that might rear their heads...
1. the length of the bullet is going to require a faster twist to stabilize that long og a projectile. I think that people are areasy shooting the long Bull Shop from a 1/28 it is just a matter of achieving the velocity the twist needs to stabilize. I think we all know the 1/24 does the best overall job of providing stabilization to longer bullets.
You mention the 1/20 twist and I am not so sure that might not be to fast for a long lead conical. The general rule is that if you
under-stabilize a projectile accuracy goes to pot... and theoretically there is no such thing as
over-stablization - but I think there really is... and that is part 2
2. bullet consruction can really effect stabilization. If shot from a twist to fast the bullet is set to spin so fast that imperfections in the bullets contruction will be magnified and 'wobble' induced by the spin will appear.... causing a loss of accuracy
Just running off - so if your thoughts differ - go fer it... I certainly do not know it all like another on this site...
