I got a new AR-15 and I bought some nice 62 grn bullets. I figured I would sight it in with some factory rounds and then try out some hand loads.
So, I went by the Lee Reloading guide and loaded some Varget loads and some IMR4198 loads.
My Varget loads were from 22.1 grn to 24.1 grn. And my IMR 4198 went from 18.5 to 20.5.
I know that you can typically shoot slightly compressed Varget loads, so I may go up a little to some load data I found that went to 26 grn...
My initial thought was that varget would push more and the 4198 would have some kick. In my 45-70, the varget rounds push and the 4198 round KICK...
Well, long story short, the IMR 4198 burns way to fast and would not cycle the action properly so the cartridges got stuck. And the Varget rounds shot like a dream!
So, its Varget in my AR. ;)
One funny observation is that a lot of people shoot 5.56/.223 and they just leave their brass. So, I pick up a ton of brass every time I go to the range. Anyway, I clean it and throw away anything that looks even remotely suspect.
