David, I have been telling you that you can shoot when you focus. Now maybe you will start believing me.
In the FWIW department, my databook shows:
175 SMK
41.7 IMR 4064
at 2.870 COAL
as the tightest grouping 175gr load in my remmy 700p using that bullet.
That is your group #3 plus .070 length but I wouldn't read anything into that .070 except a little less velocity.
I'd rather be lucky than good, but I'd rather KNOW I'm good than HOPE to get lucky.
TS - what rifle are you shooting? Looks pretty darn good to me!
I'm parking this 175 fggm replicant info here that I found recently.
