They still exist! It would be the Traditions Mountain Rifle. But, they only come in 50cal
 
Congratulations! Your rifle is a beauty!

Regarding ball size, CVA recommended a pure lead .562" ball with patches of .017" to .020". I have the manual right here in front of me, and that's what's in the chart. As for powder charges, they recommended starting with 60 grains of FFg, up to a maximum of 120 grains of FFg.

It isn't discussed much because these rifles are really not very common, but it is pretty generally known that the .58 caliber CVA Big-Bore Mountain Rifles were not true to size, but ran somewhat under. This is why CVA recommended the .562" ball. I have one of those rifles, assembled from a kit, and had a gunsmith check the bore for size. He found the bore was .575". I think a .570" ball might be pretty hard to load. If you cast your own, also bear in mind that round ball moulds are sized for pure lead. I have a quantity of lead salvaged from a cowboy action range. It is harder than pure lead, and I have found that balls from it drop out oversized, around .602" - .603". Others have reported similar results on this forum.

So, if you already have a .562" round ball mould and pure lead, you should be good to go.

As a final thought, Deer Creek Products has digitized all of the old CVA manuals and put them on their website. It's always a good idea to at least take a look at the manual.

Best regards,

Notchy Bob

Why 562? Personally I want something more than my 54, so would want at least 570.
Because many of the CVA Mountain Rifles have a slightly undersized bore. Mine does great with a .562 ball .010 patch and 110-120 grains of goex 3f.
Tried .570 ball and a .005 patch and couldn't get it to start and didn't think that a 5lb sledgehammer would be either a good idea or practical to carry Elk hunting.

Well, a .562 ball is more than a .530 ball lol. At any rate my 58 Mountain Rifle seems to like the 440 grain L.E.E. R.E.A.L. bullets just fine and I am sure the. 562 roundball or the R.E.A.L.'s will put them down right quick.
 
I think a rifle that a person might use to hunt bear, bore or any type of possible dangerous game should load fairly easy so a .562 ball if accurate makes sense. I prefer a ball that a short starter is not needed and also less stress on the ramrod.
