I’m in agreement with LC here. Most of my guns have conventional crowns. I own two that are coned. One that was done by Getz barrel co. One done by me useing a lathe and four jaw chuck with a carefully ground boring tool. All my guns shoot as good as conditions and my eyesight allow. I still use a short starter as I like to use prelubed seated ball blocks and paper cartridges of powder for hunting. BJHProbably depends on the quality of the work. I've never coned or had it done. I do rework the crown on all my barrels and find the idea of coning intriguing but don't want to risk doing it.
