Good evening, today I found in my local gun store an offer of lyman molds (50% off), I have a cz 550 varmint that I usually use with Sierra bullets, but I felt like buying one of these to see how it shoots. The cz is 1:10, so I think these are the molds that best fit the ones you have for sale. I really liked 311466, but I better listen to those who have already used these molds, remember that I'm going to use it with an Argentine powder gun that is similar to 3031
311466
311291
311332
311644
Which one do I buy?
