Bore Buttons do make a difference.

I use Oxyoke wonderwads with every round ball hunting load in all my rifles, but not with PRBs in my smoothbores.

Interestingly, my .54 and .62cal flint smoothbores get an occasional flyer with a bore button...if I remove it the flyers go away...patches still survive fine so I shoort PRBs out of those smoothbores without a bore button.

In my rifles, I actually use the next larger caliber size bore button:
.62 in a .58 - .58 in a .54 - .54 in a .50 - .50 in a .45
I figure since they improve accuracy by serving as a firewall to protect the patrch AND make a better gas seal, then a larger one that gets squeezed out into the grooves themselves should even be better...a tighter seal, more lube, etc...no science to this, just my assumption that if some is good, more is better...works fine.
