I want to start using my 311x291, 311299, 311284 molds and unique powder to use in my chinese sks. These are the only molds and powder i have and have used them for about 30 years in my No4 mk1 303. Ive run out of cheap ammo for the sks and still hunt goats and red deer locally, I recon the sks using cast boolits could be the answer. Any advice from the members will be greatly appreciated . The 311291 is a hollow point and casts about 155gn, the 299 casts about 205, the 284 casts about 218. I use wheel weight dropped into cold water.
