With 69s at 600 yards, I can barely tell the difference between the first 2 batches for 10 rounds, the 3rd opens up a few inches. At 200 yards, with 55FMJs of the same style with the same load, the difference is maybe 1/2" across all three batches. I shoot more of that 3rd batch than anything in matches since most are lost brass.

If you want to try 20 of each for your loads, let me know and I will bring you 3 baggies to try them out. The chamber may have some effect on the reliability if it is a tight .223 chamber.
These are only going to be blaster ammo. Since I just begun loading .223, I started with once fired brass and completely prepped 100 pieces. I did this because I want to see what type of accuracy I can get out of these loads but, in the future, I just want to make all of my .223 cartridges in a progressive without having to do any prep (if I can get away with it).

I have heard that RCBS makes a die called the "X-die" which, after trimming the brass once, it will keep it from "growing" when full-lenght sizing. I was thinking of picking one of these dies up.
