303 mill spc im sure used to be a very big bullet over 200gn im pretty sure in later years they droped it to arround 170gn an expert could tell you more
I had a p14 and i ran that on 175gn smk bullets i think cant remember for sure but the gunsmith told me to shoot heavys for best accuracy to keep with what it was dezined to shoot
