LSWCs (Penn / Missouri / Magnus / Zero) Accuracy

First topic message reminder :

After reading the pet loads by the Masters it looks like Zero and Magnus are very popular, but I didn't see much mention of Penn or Missouri bullets.    The price for all is about the same for 185 gr or 200 gr LSWCs and I've heard of other shooters using Penn bullets with success. Are the Magnus/Penn superior over Penn/Missouri LSWCs? 

Cheers,
Derek

Looking at the Magnus bullets, do folks prefer the 801 (button nose) or 808 (long nose) for 185gr? Are there feeding issues with the button nose version?

Seems that the button nose is a flat base while the long nose is a bevel base, not sure if that makes a difference or not...
