Getting Back into It

[Kurt]

Welcome Dan.

First I don't know what PPB is.
Your getting 2 3/4" vertical with 1.5" wind @200 I would say that that is pretty respective.
Your groove diameter patched bullet will shoot good but you loose a lot of powder space unless you have a considerable amount of cylinder free bore that will let you seat the bullet farther out of the case.
Most including me shoot bullets patched from .002" under bore diameter to maybe .001-002" over bore diameter this will let you seat the bullet out to get more room in the case for your wad stack and powder.
I match loads are patched .001" to .002" over bore diameter for my chamber design I use.
