So, I have been playing around with cast bullets in a couple pistol length 300 Blackout AR's. When I can get them to completely go into battery, they are a blast. Problem is that once powder coated they are mostly a little thick in the nose area to function dependably. So this morning I pulled all my 30 cal molds that I have been playing with to do a side by side test. All cast from the same pot of range recycle lead and a shot of tin to help with fill out. Now these are not the prettiest bullets and that is no fault of the molds. didn't have the time to get all five up to perfect temp. Once they started throwing decent bullets, counted bout 50 and on to next mold. two mold are from NOE ( one brand new), two from Arsenal molds and one from Miheck. weight's are from 135ish thru 188ish. Will weigh and average the bullets. Biggest thing I want to take from this is which ones have to smallest diameter nose area for reliable feeding after powder coating. AR's just don't have the camming ability a bolt gun does. So tight doesn't work well. All of these bullets I have shot ( except for the NOE) and have worked good with LilGun, just haven't had reliable feeding. also going to try a few different colors of powder coat ( mostly smokes, but a few others) to see which one's go on the thinnest. Here is a picture of the lineup. Will post more info when molds cool down. Anyone know how to rotate the picture's?
