Nice looking bullets Corey. I have been casting my ML bullets for a few years now. It is and art and patience is a required necessity. That R.E.A.L bullet is one that I use in my Hawkens Carbine in .54 cal. It shoots very well and I use it for my practise rounds in this gun. I normally shoot a Barnes Expander sabot during hunting season.
Where are you getting your lead? I am constantly looking for wheel weights or scrap lead whenever I can. A friend of mine just did a job at a hospital and gave me a bunch of sheet lead from the Xray dept walls. It is very useful and pliable to work with.
Do you shoot at a range of some sort? You may be able to dig up and recycle lead bullets from berms. This lead would be fine, but you wouldn't be able to know the actual hardness though unless you have a tester.
