Thanks guys! still don't understand the large difference in ball sizes though. I use .600 balls in my 20 ga. with great success. I keep hearing .715 and .735. why not a .730? I was always told to go .20 under bore size for smoothies, and .10-.15 under for rifles, and this makes for easy loading and the accuracy is great and as good as I can shoot in my guns. the mould sizes I see offered are also .715 and .735, and that's all I find! Someone please teach me what the deal is, I need to get this right, and don't want to spend any more than I need to too find the right load. Plus, I hear Ray Rapine is close to the end with his buisness, and want to get a mould for the .75 before it's too late. I have his stuff in .440 .530 and .600 and all work very well as long as you don't let them heat up too much. Keep it coming guys, I really apprecieat it! :thumbsup:
