Hi guys I have been eyeballing these two molds lee C312-155-2R (90741) and the CTL312-160-2R (90579). I was wondering if anyone has the two of them and if they are basically the same size bullet. I am looking to cast them up for some 300BLK and 7.62x39 and PC them for a semi. I have heard ok results on the 155 grain but honestly nothing on the 160 tumble lube. I was under the impression the tumble lube bullets where better for Powder Coating. Any thoughts would be great. Probably the same and I am looking into it to much but I have some time.
