You didn't mention what the rate of twist was and if you are shooting conicals. I pure my own R.E.A.L bullets. I have a 1 in 24" twist rate and normally shoot the Barnes Expander Sabot during hunting. To go cheap the rest of the year, I practise with the conicals. I am using a Lee Mould for the R.E.A.L bullets.
Now on my .58 cal. I use commercial RBs. I figure it is cheaper and less time consuming to go commercial. And this give me more time to make them conicals.
