Button or Cut rifled barrel

[JCP]

A while back I used a couple of Green Mt. cut rifled chrome moly barrels to build two nice 45/70 rolling block rifles. I'm very happy with the ones I have, they just cost a lot. This time i'm thinking of trying their Chrome Moly button rifled barrels, any of you guys tried them? Should the accuracy be as good?

I'll be shooting black powder, lead bullets ,and some paper patch. This one will probably be 45/90.

IT WOULD DEPEND ON WHAT YOU EXPECT OUT OF THE BARREL. I THINK IF YOU'LL CHECK YOU'LL FIND THAT THE BUTTON RIFLING IS NOT AS DEEP AS THE CUT RIFLING.
  CUT RIFLING MIGHT BE BETTER FOR CAST BULLETS. MIGHT IS THE KEY I'M NOT REALLY SURE. TRY ASKING GREEN MOUNTAIN AND SEE WHAT THEY SAY.

It isn't the type of rifling that counts, but the quality of the job. Pope was one of the greatest barrel makers of all time and he built a BP Scheutzen Rifle that was rifled with 80 grit emory paper and it shot as well as his broached barrels. There were only the striations from the paper to give it the proper twist. No lands and grooves. A proper fitting bullet will do the job with lead. Jacketed bullets are forgiving when it comes to groove size.
