Sellior & Bellot sells a 180 grn flatbased round nosed ammo that seems to work the best in tired bores.

Give the bore a good clean and blatt off some cheap stuff like ex military ammo. I have found that rough bores might need 50 shots to "season" , that really means shooting off the loose shit the bore brush didnt shift and filling the worst pitting with jacket material.

If you do use millitary ammo, pour a kettle full of boiling water down the bore afterwards. Let it cool then oil and put away.
