Ive been shooting STS and Nitro 27's out of my 12Ga. 20inch cylinder bore Ithaca,
I have no problem ejecting quicky,
when i went over to fiocchi and Cheddite tall hulls, i started sticking,
even in my cimmeron SXS clyinder bore this is with low published data loads,
the hulls are flaring out at the top edge, I can feel it, a cutting edge, and catching in the bore,
the short hull/real brass/ are not doing this
im thinking i need to do a polishing of the Ithaca, in the chamber, I can see machine lines, the bore is silky smooth
Do I use the long hard brake hones ?
or
the multi ball brake hones?
common sense tells me the long hard ones would leave a mess at the forcing cone,
