Hey guys. I have been casting pistol bullets for about a year now and I have thought about getting into casting rifle as well. I was going to try casting for my AR 15 in 5.56 but after researching it the extra trouble of gas checking those little bullets doesn't seem worth the trouble.
I have decided to build a 300 BLK with a 16" barrel. I have started shooting a local 3 gun close quarters tactical match. I am interested in making some cast loads for the 300 BLK to help cut my costs. I have no plans to run a suppressor but I mainly interested in the heavy 220 bullets. I coat my pistol bullets with the Hi-Tek coating and I would imagine it would work fine for the slow heavy bullets in the 300 BLK.
The farthest distance we shoot is maybe 25 yards with a rifle so I am not interested in long range accuracy with this load.
I have been digging trying to find all the info I can before I spend a lot of money. It looks like Reloader 7 works well for the heavy bullets. But there isn't a lot of load data I can find. All the guys I know running the 300 BLK use jacketed bullets. I am concerned about leading and cycling and of course it has to be reasonably accurate. Thanks for any help.
